Easy peasy

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.

Good attitude, still not sure if there will be any additional charges

Overall satisfied.

The car had many minor scratches that needed to be carefully checked, photographed, and then confirmed in writing with the staff in the hall. The store at Madrid T1 is a long walk from T2, and there were many people in line, possibly because it was Sunday. The car we got was an older, basic model.

The process was quite convenient. They asked for the order, driver's license, passport, and notarized documents, then only inquired about additional insurance (I guessed, as my English isn't great). I declined, swiped my credit card, got the keys (which had the parking spot number), and left. Originally booked a BMW 3, but got a new Lada with only 1700 kilometers. Returning the car was also very easy; I just said 'done' to the staff (non-native speaker), they checked the car with a device, and it was fine. Back at the office, they gave me a receipt.
