Be aware that this company will charge you extra (250 zl) for outside working hours. The working hours are not announced. It is not on their door or on website. Do not use the drop box for keys. This means you will pay extra.

Also, if you don't clean the car, they will charge you.

I don't know what else is hidden!

This is what I was told by the manager:

"It is writen in the contract in terms and conditions."

I recommend you go for well known rental companies. Everything is clear.

O stars, did not return my deposit despite contacting them several times, extremely rude and arrogant, claimed they paid it back and said my case was closed. Rude and unhelpful on the phone. Contacted the owner Rafal Niemiec on linked in, no response either. They also charge you for cleaning the car! Thieves.

Five star experience.The car was modern and clean.The pick up and drop off went v smoothly.They were very helpful.I would use there company again if I visit Poland again

Watch out!!! They are not are the airport as they mention. This is the car rental company you can book through Booking.com, but Booking.com will not protect you against this scam.
Being 13 minutes away from airport means you have to wait for them to pick you up at airport with a van, as there are no many employees, you will have to wait long cue to be attended at their office, and the same for returning the car.
We almost missed our plane!!!
Not a single sorry from them, I heard. This is what it is.
Don't hire this service and don't expect Booking.com to cover or compensate to you
