I've had issues both times at this rental car company's airport pickup point. If you pick up the car earlier but return it at the same time (e.g., booking from 10am to the next day 10am, but picking up at 8:30am and returning at 8:30am the next day), you will be charged an extra day's fee. Take note!!!! Additionally, the airport branch's working hours are until 10pm local time, and picking up the car after 10pm incurs a service fee of 36 euros. Sharing my 2 experiences for your reference.
