I've always used Europcar; their service attitude is genuinely great.

Very good. The location of the car return parking lot at Paris Orly Airport: Google Maps navigation is not accurate. Even if you set it to 'Parking P3 - Parking Officiel - Aéroport Paris-Orly,' after entering the airport highway, you should turn left to enter the parking building. However, the navigation keeps directing you to turn right, preventing you from entering the building and leading you to circle around the airport. Trust Waze navigation; it is much more accurate. Alternatively, follow the ground signs for P3 and the 'Location Car Rental' sign ahead, which will lead you directly into the building and to the underground parking on the 3rd floor, where all the rental car parking spaces are located.

We had a lot of luggage, and they took us to see the car for confirmation. The car at our selected price range was unavailable, so they upgraded us to a Renault Cabin. It needed a wash before we could use it, which required a 30-minute wait. However, the staff was friendly and patient.

On m'a chargé un surclassement sans m'en avertir!
