The same attendant handled both the pick-up and drop-off, and he was quite unprofessional. It took almost half an hour to complete the paperwork, and others at the rental company seemed embarrassed for him. He was very slow and dragging his feet. Eventually, another female attendant processed the pick-up in just 2 minutes. The same thing happened during the drop-off – there was nothing complicated, just needed someone to check the car, which took over 10 minutes to arrange. After the inspection, there were no issues, but he went off to do something else and took almost another 10 minutes to finalize the paperwork. If you rent a car at Athens Airport, try to avoid this company if possible. If you encounter this specific attendant, you'll need patience and a good temper. If you're in a hurry to get to the airport, it could be troublesome.
