Guerin Reviews 

By Guerin is very simple to Rent a car, the Personal is friendly, the Service is very good and the Cars are like new, i am very satisfied with them 👍🙋🏻‍♂️

Too much waiting to get the car at pickup and at return big problem inside the parking where it took a long to drop the car

No issue with car rental. Smooth process, friendly staff, the process is clear and explicit, no hidden costs or anything.

Overall good experience with my car rental from Geurin at Faro airport in Portugal.

I did book a Seat Ibiza (or similar) and was given a Kia Picanto which was fine, car was modern and drove well. Few scratches and scrapes along the vehicle but this is to be expected on a rental.

Collecting the vehicle upon arrival was a bit tedious, I booked online so having to fill out info on a tablet upon arrival to then have to take my receipt to a separate counter to queue and collect keys seemed a bit silly. The process took maybe 30 minutes when it felt like it should've taken 10.

Drop off at the end of my holiday was far more stream lined. I handed over my keys to a member of staff and he took a few minutes to walk around the car, said everything's good and I was on my way.

Car ran as you'd expect, no issues during my time with the vehicle and Geurin provided details on how to contact them incase any problems did occur. Overall I'd recommend Geurin if you're after a budget friendly rental option, the convenience of them being directly outside the airport was also a huge bonus!

Simple and uncomplicated processing. Fair price and helpful staff.

So we rented the same car from their service three times and they gave it to us dirty every time. When we returned it they said it was dirty so they're going to charge us for not having it cleaned despite the fact that they didn't give it to us cleaned three times in a row. Which is deeply frustrating.

I was hoping that this company was going to be different compared to other car rental companies but unfortunately they're not. The manager was extremely unfriendly and if I can give this a zero I would. This is a very frustrating experience for us because we've been long-term clients with them and rented quite a few cars from them but this might be the last time for us.

During vehicle return, the staff claimed that a dent in the door had been caused by me. Fortunately, I had taken a video at the start of the rental and managed to find one frame where the dent was visible at the right angle. Without this, I would have had no way to prove it was pre-existing. It also seemed like this dent was not being properly logged into the existing/known damage list, which raises concerns that the next customer could be charged for it instead. This practice feels dishonest and unprofessional. Without my video evidence (and some luck with the camera angle), I would have been charged for damage I did not cause.

I rented a car that broke down after 100km on the highway; when I called road assistance they told me I should drive the car if it is still somewhat rolling. The only solution they gave was waiting for 2 h for the tow truck to be towed back to Lisbon to change vehicle. Until today no sort of compensation or response about the fact that they rent cars with technical failures.

I had a great experience with Guerin at Madeira Airport.

The booking and collection process was smooth, the staff were friendly and professional, and the vehicle was exactly as described. I was given a BYD Seal U which was clean, comfortable and in excellent condition.

The return process was also straightforward, even though I returned the vehicle outside office hours. All documentation was provided promptly and the rental was closed without any issues.

Overall, a hassle-free experience with good customer service and a quality vehicle. I would happily rent from Guerin again when visiting Madeira.

Thank you to the team for making the process easy and stress-free.

Terrible experience with Enterprise/Guerin at Porto Airport.

I rented a car from June 7 to June 12, and I deeply regret choosing this company.

First, I was charged twice for the Transborder Charge, resulting in nearly €40 in incorrect fees. In addition, although I paid €245.87 on June 6, I still have not received the corresponding rental invoice.

Even worse, another charge was made to my account on June 20, more than a week after I had already returned the vehicle.

As for Guerin customer service, it is virtually non-existent. It is impossible to talk to them over the phone, and my emails have gone unanswered. When it comes to taking your money, everything works perfectly. However, when a customer requests an explanation for questionable charges, nobody seems willing to help.

This experience reflects a complete lack of transparency and customer care. Between the duplicate charges, late withdrawals, missing documentation, and the inability to reach anyone for assistance, I cannot recommend this company under any circumstances.

Avoid at all costs. If you decide to rent from Enterprise/Guerin, carefully monitor your bank account and keep every document and receipt, as you may need them later.

We rented a car from Guerin at Faro Airport and everything seemed ok until we discovered several days later that they had added 280 euros to our bills for extra insurance . We were never offered any insurance and don’t need it because we have excess insurance. When we challenged it they produced an electronic document with a cut and pasted signature to say that we had agreed. This forged document meant we could do nothing. Guerin are routinely forging paperwork to justify scam charges. If you look on TrustPilot Guerin are making scam charges for tolls, damage on return and o5her things. Terrible scam operators avoid at all costs!

Quite interesting to read a previous review regarding a front rim. I had exactly the same problem when returning the car today. An apparent scratch on one part of the passenger side front rim. If anything, I would have expected that sort of damge on the rear wheel as I had reversed into every parking spot when near a kerb. We noticed a scratch on the rear. We told this to the representative when we picked up the car & he said any damage would be in the damage report. It was not mentioned, & we had to wait 5 days for that report too. When dropping off the car, this scratch was missed. I would advise people to avoid this firm as they appear to be selective in their inspection & now I'm 200EU lighter in the pocket

When dropping off the car, the guy looking over the car was overly thorough which I found odd. He carried some iPad and went over the car all over the place. This never happened before with any past rentals. It seemed he was looking for something to charge me. And he did! Apparently I scratched the driver front rim. Really??!! I told him this is not from me. But he spoke to the cashier inside the Guerin booth and they placed over 200euro charge! Scammers! I have since informed my bank to reverse the charge and they are looking into it. Common knowledge for Europeans is that North Americans have insurance. So they feel the need to scam our system. I asked Guerin to send me before pictures time stamped as to when I took the car as they are so diligent in reviewing every inch of the car, but no response! I also tagged in the Portuguese Police, they gave me a wrong website to lodge the complaint! I have yet to hear back from anyone one of them. DO NOT USE GUERIN. THEY ARE NOT TRUSTWORTHY. BEWARE. DO NOT BOOK WITH THIS COMPANY!!!!

My $250 euro rental ended up close to $625.00.
They upgraded us without permission, and it was to a lesser car than reserved.
Then the extra charges started hitting my CC.
They said to advise on return, I did, they did nothing and were extremely rude.
These people are thieves.
AVOID!!!!

PLEASE READ ALL OF THE NEGATIVE REVIEWS ON TRUST PILOT ABOUT THIS COMPANY!!!!!!!
Like many others have mentioned they will try and sell you additional insurance so you do not have to pay the excess in the event of an accident, despite us showing we had already taken out a comprehensive insurance with no excess via Booking.com through Zurich Re. We were also told not to worry what state the car was in, as we were covered whatever. Even when I decided to take photos of the existing damage I was told that it wasnt necessary as we had the top cover, as our vehicle had been parked in the road way and others where wanting to pass we drove off without taking photos! (BIG MISTAKE). On our return...Guess what!! scrathes apparently. We had hardly used the car and was not aware of any damage. When we arrived back at the airport one of the Gurin team looked over the car and we noticed them taking pictures and typing on a tablet. I asked if everything was ok and was told yes apart form a few scrathches, i asked where and he pointed to the front passenger wing, ignoring all the dents and scrapes over the rest of the vehicle.
I would NEVER use Guerin again and I would also not book through Booking.com as they were not interested in our complaint. My advise would be to read reviews and book directly and 100% take photo BEFORE and AFTER returning the vehicle, regardless of what insurance you have taken. The additional protection that we reluctantly agreed to is expensive and I fail to see how this would have worked in the event of a claim other than having to pay the full excess. I would guess that even if we did scratch the vehicle this would not have exceeded the excess and we would of paid this on our credit card and claimed back from Zurich re. STAY WELL CLEAR OF GUERIN !!

I rented a car from Guerin with their most complete insurance package (Pack Premium Gold), which is supposed to cover all mechanical breakdowns.
The car was rented for a trip to Spain. When it developed a fault, I had to drive it back myself from Spain to Portugal to swap the vehicle. The return document stated "No new damages" and full tank.
A month later, Guerin charged my card for "wrong fuel in the tank" and a full fuel replacement.
I asked for a workshop report, a fuel analysis, and an invoice for the alleged work. They provided none of it and kept ignoring my messages. After I escalated the matter formally, their entire response was a photo of a bottle with some pink liquid.
Lesson: even with their most expensive insurance, if something happens to the car, expect a charge on your card with no proof and no explanation.
