Guerin Reviews 

Very quick, great value and great location and staff.

Excellent, nice and easy

The final confirmation did not mention the type of car. The email didn't either. Can you contact me to confirm the type of car?

Avoid Guerin in Madeira. The car broke down during the rental and Guerin demands that I pay over 1500 euros to repair the internal damage to their car, even though this is not included in the rental terms.

By far the worst experience with Guerin car rental in lesbian Portugal , where 1 star is actually too much.
Dear people. If you end up at this company to pick up a rental car, try to get another Our rental car was vandalized and we were charged $830 in repairs broken window , We’ve spent 2 weeks trying every possible way to reach Guerin for the documentation our insurance needs, and they have not responded once. No customer service, no support, no resolution. Extremely disappointing—avoid this company at all costs.

My problem is how can Guerin incharge my credit card without any authorisation after 8 days since car was droped?
Yes IT is posibile, they have an agreement directly with Mastercard.
So be careful and avoid this by keeping your data card secure.

Good and quick service by the employees and online check-in is good

I was charged twice for an additional driver because I had forgotten my driving licence when collecting the car in coimbra. Your customer service informed me that this is stated in the small print and therefore I am not entitled to a refund. However, this condition is not mentioned anywhere, yet I have still lost my money.

*Later on, the money I had overpaid was refunded to me after all.

We booked a car for 8 days from Lisbon Airport ahead of time with Enterprise. Full cost was £177.53 for "Hyundai Kauai or similar" (which has a RRP of £30k). We included ALL options for cover - there was nothing we did not opt for. There was no mention that more costs would be due at airport, or that this service would be provided by anyone other than Enterprise.

On arrival..

* the service provider is actually a local firm called Guerin (NOT enterprise).
* the car was a Seat Arona (RRP £20k). So the car we were promised is 50% more expensive than the one provided. This is NOT "or similar", any more than Ronnie Corbett is a "similar height" to John Cleese.
* We are presented for the first time with the news that we have no insurance, and must pay extra for this. The cost of insurance for 8 days was pretty much the same cost as already paid: Euro192 - roughly £170.

At this point we had no option but to pay.

So you get half the car for double the price. Avoid at all costs. Hertz were onsite at Lisbon airport, and I doubt would pull such a stunt.

Absolute sharks. I returned my hire car to Lisbon airport. There was a tiny mark on the sidewall of the tyre, and they said the whole tyre had to be replaced. The charge for a single tyre? €475! What an absolute farce. It's clear that Guerin/Enterprise don't value their customers and just want to take any opportunity to rip them off. I asked the manager on duty to how they could justify such rip off prices, knowing full well a replacement tyre wouldn't cost anything near this price and she just shrugged it off and said 'claim on your insurance', as if it didn't matter I was being ripped off because my insurance would cover it (I didn't have any insurance to cover it).
I complained and she gave me the customer service email and said contact them. I have sent four emails now and heard absolute nothing back they just won't respond and have ignored every email.
I was regular customer or Enterprise/Guerin and feel badly let down by them being ripped off and now being ignored. I will never hire from them again. AVOID AT ALL COSTS. If you do have to use them, make sure you have cover to reduce the excess to €0, because the will fleece you hundreds of Euros for the tinniest mark/damage.

Absolute worst treatment I have ever received anywhere. The manager at Guerin in Faro was beyond rude. I am handicapped, and my cards were not being accepted, even though they were valid, and had enough credit to cover the costs.

I was sweating, out of breath, and treated poorly. I was offered no assistance, and the person moving me around in a wheelchair was only authorized to take to to the exit of the airport. I was on the verge of a serious medical issue, for which I was presented with a complete lack of empathy, and understanding. A simple ride back to where my wife was waiting would have resolved the situation. Our initial flight was delayed by 4 1/2 hours because of an administrative issue, and as a result we were seriously delayed, exhausted, and treated like dirt when we arrived to retrieve a car. No chair was offered for me to even sit down, while it was clear I was in pain, with an elevated heartrate, sweating, and out of breath because of the long walk to the rental location. Guerin have basically stolen my money.

Booked Alamo through a third party website and as we were in Portugal, it assigned us a Guerin car. Honestly no complaints, got nervous handing the car back purely because of the reviews (the car was in good condition) but the guy was fab that we handed it back to, only charge after handing back was for tolls as expected. Great experience, no complaints!

Worst car rental ever. Website has wrong info about pickup, they close at 11:30pm with no after hour option (website is a lie). staff doesn’t care. Any number we tried calling, including the emergency number during the day or evening, no-one answered!

By far the worst experience with this car rental company in Portugal!!, where 1 star is actually too much.
Dear people. If you end up at this company to pick up a rental car, try to get another company through your booking agent.
We booked our vacation with Eliza was here and got a rental car through this company. It was a Hyundai I20. Check-in went fairly smoothly, but it was very rushed. We had to quickly take photos of the damage to the car, otherwise we would be charged for it upon return. We did so. We had to drive an hour and a half to our holiday destination and after 45 minutes we realized that the car only had a quarter of a tank of gas. It had not been filled up when we picked it up. We called and emailed Guerin, but no one responded. Even the emergency number was not answered. We explained the situation to Sunnycars in the Netherlands and they told me when I returned the car that everything would be fine. Filling up the car cost me €50.01. The day before returning the car, you receive a rather aggressive text message telling you that you must return the vehicle with a full tank, otherwise you will be fined €36.90, which will of course be deducted from your credit card deposit, plus the cost of the fuel, of course. Guerin's rental agreement also states that the fuel policy is that you receive the car with a full tank and must return it with a full tank. So, I returned the car with a full tank. Upon return, the car was meticulously inspected for damage and other issues. Strange! Because the car is fully insured through Eliza. I really had a gut feeling that they wanted to deduct the cost of any new damage from your deposit in order to line Guerin's pockets. At the counter, I met Chantal Oliviera. I told her the story and she saw that I had sent an email to Guerin on the day I picked up the car. But as expected, there was nothing she could do for me. I'm not going to get my 50 euros back. I was supposed to receive an email from her manager the next day. I did receive it. It was just an apology and that they regretted how things had gone. And then you get a kind of voucher that allows you to rent a car for one day free of charge with an upgrade within a year, subject to availability at the location. I don't want that at all. I just want my 50.01 back. I am fully entitled to it according to their terms and conditions. Chantal also told me that the person who rented the car before me had been fined 36.90. And then, of course, there are the costs for refueling, which was not done. Just imagine how quickly Guerin tries to rip off their customers in every way possible. Not to mention all the damage to the rental vehicle that was not repaired. But they did keep the deposit and claim it from the insurance company. In short, you have been warned not to rent from these scammers!!!!!!

Two weeks after my review, they responded, saying they were sorry and that this wasn't their normal course of action. They also wrote that if I needed more information, I could contact them directly. But how? They don't have a personal email address, and they don't answer the phone. I JUST WANT MY 50 EUROS BACK!!!!

Avoid this company. They withheld my €600 deposit for false reasons, including a €75 charge for wiping sunscreen off the dashboard! Their damage photos didn't match my own from drop-off, and they have ignored all my emails disputing the charges. This appears to be a deliberate strategy to take advantage of tourists. Take extensive video evidence if you rent here, but better yet, rent from someone else.

This is my second experience with Guerin, Lisbon in 2024, Faro airport in 2025, and each was excellent, very pleasing. The check-in was online before I travelled, the office was a short stroll across the car park outside Faro's lovely terminal building, the final process was on a screen with a member of staff to guide me and I had the keys.

The car (Renault Captur) was clean and ready to go, it worked well for the week and the return procedure was quick and painless.

Friendly and efficient staff made the experience enjoyable.

Thank you again, Guerin!

SCAM! DO NOT RENT Here! Booked through Expedia. Pickup: Car was damaged scratched they said don’t worry it’s all on the report. Returned with full tank of gas and had video of the car because we dropped off before they were open. We got a bill saying we damaged the vehicle. I tried to contact through email Facebook and mailbox till no response mailbox full . I contacted Expedia they said they billed me for not filling up the car with gas, so another lie. They charged my credit card for gas and damages and I am currently trying to dispute with the card company. Do your research I see on tiktok they are scamming people!!! Now searching other reviews they are doing the same scam to tourists! Horrible and no customer service available. Worst company!!!!

My recent experience with Guerin/Enterprise was extremely disappointing. I rented an electric car to get around Portugal for two days due to a family emergency, but I was very frustrated with the lack of charging options. The car didn't include a cable for home charging, which seemed essential to me, and the company didn't even offer it as an extra. This left me in a difficult situation, as public charging in Portugal requires a contract with an energy supplier, which I didn't have. The customer support was useless and didn't help me solve the problem. I felt completely unprepared and frustrated, which negatively affected my trip. I wouldn't recommend this company to anyone looking to rent an electric car in Portugal, especially those with an eco-conscious mindset and a concern for the world."

When hiring car, I purchased add (or it was included) for all tolls to be paid automatically.
The tolls weren’t paid at the time of my using the car. After the hire, my credit card details were used to try and pay them. These were rejected because I had since got a new credit card and the old one had expired. Guerin didn’t tell me this until long after a fine had been issued directly to me rather than to them.
I emailed them and they asked me to pay the fine and then would pay me back. I gave my bank details in June and have chased once a month since then. 5 chaser emails and no reply. Do not hire cars from this company. All the other reviews demonstrate that this is not a trustworthy company.

At the time of return and after I had signed, the man told me that I was being charged €75 by Guerin because they claimed there was sand that needed to be vacuumed, even though they vacuum and clean the car anyway. On top of that, there was a €30 fee for this sand at the bottom of the car. The car had rubber mats for that exact reason. The car is also marketed as an active vehicle for an active outdoor lifestyle (Dacia Jogger). Having some sand in the car after a beach holiday is completely normal. I have never experienced such a charge before, even though we have rented from three other companies in Portugal on nine previous occasions. Only Guerin has used these dirty tricks.

The man only mentioned it after I had already signed. I then discussed it with several other staff members who refused to listen to me. On top of this amount came IVA, so the total bill ended up being around €130 just for vacuuming. Altogether, we were charged an extra €210 in addition to what had already been paid to Rentalcars. A completely absurd amount and utterly unacceptable! Never Guerin again. Thieves and deceitful tricks! To lure people into signing and then afterwards tell them they’re being charged a ridiculous amount for vacuuming is theft and a scam!
