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.

Overall good

Very good

The staff was nice, but the waiting time was just too long. We had to wait for a very long time. In Germany, it’s mostly self-service. They give you a key once everything is done, and then you walk to the parking lot to get the car. The Munich parking lot was the multi-story type, and after coming down, we lost the GPS signal in the congested streets. No... signal... at all, so we drove randomly for a while before the navigation started working. But the car was very clean. We returned it at Frankfurt airport; you just hand over the car, and it's done. Super convenient. Renting a car in Germany is awesome.

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.
