Guerin Reviews 

Always easy and more often than not get the vehicle you requested…
Great location for ease at Faro airport

The person who checked us in was amazing. She was friendly and very knowledgeable. Not sure about her name but she made our experience.

Guerin has been reliably excellent every time I have used it from Faro Airport. Quick, efficient and lovely people manning the desk.

The process went very well.
Thanks.

Very smooth and easy. All in all everything works really well.

Used to be my favorite car rental company (and I rent a lot). The human staff is great. However, Guerin switched to a voice bot for support. It's useless. Just another company which thinks that bots can save money, on the expense of real service. And, to top up the awful service, they never reply to customerrelations email. So Guerin, are you loaded with too much requests? Hopefully, you'll have a lot of free time soon. Poor service is safest way to lose loyal clients

The assistance to customers is very good, friendly and helpful. Did get the car in just 5 minutes upon checkion in the digital kiosk.

Nice cars available, brand new and well cleaned. Do recommend this rent a car!

Guerin was a positive surprise to me. A clear booking process and very friendly staff. The Car was good, all damages where documented. Also the return works smooth and quick, including the return of my deposit.

Best rental car service we ever had.

All as it should be. Fast check out and check in, car in good condition and clean. Will tent again with Guerin when back in Portugal

Well positioned in the airport terminal ..so no traveling to get/return car. Very friendly staff.. Quick and easy collection and return.

Well organized company with friendly and helpful staff.
Process ran smoothly and the vehicle was above expectations

I had a fantastic experience renting a car with Guerin at Lisbon Airport. There was no aggressive marketing or upselling at all. The whole process was fully automated and seamless—I got the car within 10 minutes, and returning it was equally easy. The staff was also very friendly.

Make the payment method easier whether debit or credit card.

Super fast pick up at Lisbon airport when all other rentals had long queues and customers looking very frustrated. First car I received hadn't be cleaned properly so I asked for an exchange, which was done immediately and promptly. Super kind service by the staff! I would always recommend Guerin.

No problem with the car and rental. But after the rental I sent an e-mail and did not get any answer.

Promptness

Perfect delivery process, type of car as agreed, clear, efficient and correct proces of delivery!

Avoid Guerin if you value reliable customer service.

We booked a car through easyJet Cars with Guerin for collection at Porto Airport. Our flight arrived on time on 16 July 2026, yet when we reached the rental desk shortly after midnight it was closed. Other car hire companies at the airport were still open, but Guerin had simply shut for the night.

Despite having our booking and flight details, nobody attempted to call, email or otherwise contact us to check whether we were on our way. We were left stranded at the airport with our two young children and had no choice but to pay for a hotel and taxis.

What disappointed us even more was Guerin’s response to our complaint. Rather than acknowledging the situation or showing any empathy, they simply replied that the office closes at its scheduled operating hours. There was no apology, no recognition of the inconvenience caused, and no attempt to resolve the matter.

Customer service is tested when something goes wrong. In our case, Guerin completely failed.

Based on this experience, we will not be using Guerin again, and we cannot recommend them to anyone looking for dependable service.

I met with three employees during the whole pickup and drop off process and they were all friendly, honest, and helpful. After a long flight, it was such a nice surprise to have such a seamless and convenient pickup process. Everything was explained well and the drop off met all of the instructions I was provided during the pick up. The fact there was no negative surprises was a relief and would honestly recommend going with Guerin in Sao Miguel if you are considering options.
