I arrived 4 hours early and asked the staff if it was possible to pick up the car earlier. They recommended an Audi and even though I asked twice, they said it was the same price. However, upon returning the car, I was charged over 300 euros more. The staff in Madrid confirmed that the price had increased.

Initially booked with AVIS, but remembered the unpleasant experience in Los Angeles where AVIS forced insurance charges. Switched to Europcar before the trip. Both pickup and dropoff were smooth without excessive upselling. We got the car we wanted.

The counter staff upgraded my car without my consent, doubling the rental cost. Extremely frustrating.

Very convenient

We prepaid for the full amount, but due to a flight delay of over two hours, the rental company gave our reserved car to someone else. We had to wait at the airport for more than an hour, and the car they eventually provided was very dirty, with bird droppings on it.
