Picking up the car was very smooth, but returning it at night was difficult as we couldn't find the location. We had to park the car outside the airport departure hall as instructed for returning the vehicle. We hoped the car rental staff would come and drive the car away, but they insisted we drive to the parking lot behind their office, pointing fervently in that direction. Driving from the departure hall to the indicated parking lot involved many intersections, which seemed easy for them but took us quite a lot of time. It was very stressful as our flight was about to take off.
