Guerin Reviews 

Evrything was ok and very easy procces to cillect and handover the car.

Staff, Booking process, I had to extend the contract and the Agent was very helpful.

Dropping car off took way too long, un-organized and when flying out it’s very difficult to get to my destination without risking missing my flight.

I had a fantastic experience with Guerin at Faro Airport. The car rental was very cheap, the collection and drop-off were both incredibly quick, and the customer service was excellent throughout. Everything was smooth and efficient from start to finish, which made the whole trip much easier. I will definitely use them again.

Collection and return were easy and fast, friendly staff, car was in perfect conditions and according to reservation

We love Guerin and use them every year.

In terminal-area, 5 min. by shuttle, good prices with all risk insurance, excellent staff (fast, efficient, polite)

Very efficient, good conditions of cars, drop off is hassle free - I always use Guerin when I go to Lisbon

Great value. Excellent service at the airport. Friendly staff. Efficient with minimal wait.

This company operates in an unreliable and unprofessional manner. Do not go there alone, and do not rent without documenting everything: photograph the vehicle, insist on proper invoices for any charge, and bring a witness if possible. As a woman travelling alone, being confronted by three aggressive staff members and pressured into paying without documentation was a genuinely difficult situation — not just poor service.
Roadside assistance is poorly coordinated: phone support and the on-site breakdown team do not communicate, resulting in unresolved issues and broken timeframes.
Staff conduct at the Aeroporto Madeira station is hostile and unprofessional, including dismissing documented facts and confronting customers aggressively. A supervisor was brought in on more than one occasion in an attempt to de-escalate the situation, without success.
Billing is not transparent: charges were collected on site without a proper invoice, and a later formal invoice (€496.69 for “damages” and a “damage management fee”) was issued for an incident the company’s own accident report records as unconfirmed. No supporting evidence has been provided.
Complaint handling is inadequate: a detailed written complaint received only repeated automated responses, with no substantive reply.
Overall, this reflects a pattern of unclear costs, unverified charges, and a lack of accountability. Proceed only with full documentation of every step, and consider not going alone.

Great prices, rapid no fuss pick and and drop-off. Friendly staff. Great vehicle, Sensible amount held on credit card.

Car was as described and collection and return was straightforward.

Everything went super smooth!

The ease of picking up and dropping off was amazing! The car was impeccably clean and easy to drive. Would definitely use Guerin again.

Staff were friendly and car was excellent. Only call out was i was charged for cross border insurance for the entire 8 day hire period of the car when I advised the 3 days I was crossing the border. A bit of a ripoff.

Good experience, fast service

Very comfortable car. There was some issues with the car not mentioned on check-in.
