Really easy and great value.

Picking up and returning the car was quite convenient. The vehicle was spacious, and aside from the unpleasant odor from the air conditioning, everything else was fine.

There were no designated Avis parking spots at the Barcelona rental location; the car was parked in a regular garage spot. The rental was upgraded without notice, and we only found out upon collecting the car. Because the parking lot was far from the rental office and difficult to find, we didn't bother to go back and exchange it. A silver Opel parked next to our rental shadowed us, and when we stopped at a service area for less than ten minutes, the entire car was emptied. The car lock and windows were undamaged. We reported everything to the police and found witnesses, but it's hard to say if there was any foul play, and we had to bear the loss ourselves. When returning the car, the Avis staff were also very rude. After the incident, contacting the rental customer service provided only official responses. Overall, very unsatisfied and will not use them again.

This is the worst car rental store I have ever been to. I'll never rent a car from them again. The platform said car rental services are handled inside the train station. When I arrived that evening, the store was already closed. We had planned to set off early the next morning, but since we couldn't pick up the car, we had to change our itinerary. The next morning, we went to pick up the car, but it was still closed. We asked another rental company and found out they had moved to a different location. When we got to the new location, the staff lied and said they had posted a notice at the old location (which they hadn't).

Avis in Spain could improve their service speed a bit

The store is very small and shares space with other companies. There were many people, and you need to be patient while waiting. We had an appointment to pick up the car at 10:30, but ended up waiting for an hour before getting the car.
