It's okay.

The didn’t provide the car I booked (received seat aroma) The storage space of the car given was smaller then the car selected during booking. They weren’t able to provide the booked model and/or change the cargo had to work with what we got. Also due to limited staff check out process took very long

The staff was very friendly, the pickup process was simple, and they specifically reminded me to check the car and take photos if there were any issues.

Excellent service, highly recommended for international self-driving trips

The return location felt better than the pickup location because the two women at the pickup store seemed to lack patience. I asked if they could spare a few minutes to explain how to use the in-car navigation, but she responded that they didn't even have a minute, even though there were no other customers at the time! Additionally, the rental contract at pickup should ideally include English since not many people from our country can read German, but many can read English.
