The location for returning the car at Cologne station is not clearly marked, and the navigation on the car rental app is also incorrect. It took a lot of time to find the return location.

Acceptable

Great! The car inspection was very thorough when returning the vehicle. Highly recommend getting full insurance and opting for the zero liability option.

The car rental location is inside the train station, and all the rental companies are together. It's very fast! There is a lounge downstairs to store luggage. To pick up the car, you need to go to the above-ground parking lot across the street. The staff will give you a map, it's pretty easy to find. Take the elevator up, and the elevator has a password, which is on the parking ticket given by the staff.

The service was quite fast and they followed all the rules.
