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.

The rental company proposed two solutions: first, switch to another car and pay an additional 61 Euros; second, cancel the order with no refund. I requested an automatic car, but it was denied. I called the customer service in my country for help. They assisted by submitting a request and advised me to take photos for evidence.

Acceptable

The pickup point was quite far. When we got the car, we noticed several scratches and had to go up and down several times to find a staff member to report it. It was exhausting.

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.
