Self-driving in Spain

I couldn't reach them by phone.

Picking up the car was very slow due to the high number of people. At around 11 AM local time, only two out of five counters were open. The staff was sluggish, and it took over two hours to get the car. The vehicle itself was in decent condition with various features. Returning the car was relatively quick. They offered an upgrade and insurance at pickup, but you can just decline.

I thought it was a small rental company, but the car return process was very smooth.

Very good, they do not cause unnecessary trouble. If you don't want to upgrade the car model or buy insurance from the store, just refuse.

Not satisfied, didn't pick up the car and didn't get a refund
