Everything was in the expectation

They didn't provide the car model I reserved, but the other services were satisfactory.

It was average. The process took quite a long time, and at the end, they said the pickup time was 15 minutes early, requiring an extra day's charge (early pickup and return were not allowed). They persistently pushed insurance; you need to be firm in declining. The counter only handled key collection, with no staff accompanying you to the car, which means if there's an issue with the car, you have to walk back a long way to find them.

The staff at car pickup was very friendly and professional. The process of both picking up and returning the car was very quick.

The process for getting the car was good. I had trouble finding the drop off and the staff did not help much even after repeated calls. Almost missed my flight from DUS.

Ended up with a Mazda 6. An amazing car. All sorts of extras that made driving easy.

Was a great experience.
