When we arrived at the airport it turned out that the car we booked and paid for in advance wasn't available. First the service employee tried to let us pay for an upgrade to a car we didn't want (SUV instead of Sedan). Next she offered us the 'free upgrade' as it turned out the car wasn't available. Be prepared that if they say the full-coverage insurance is 'only' 27 euro a day this does not include the airport fee (%) and taxes making it in reality 38 euro a day. Furthermore, the parking lot is very tight and hard to get out of, evidenced by the car paint on both sides of the ramp walls.
Positive points: easy pick-up and drop-off, car was nice and clean, there is an easy place to refill next to the drop-off.
