Not bad but it would be better.

No hassle, handed over the documents, took the car, very convenient

Overall, the service was quite rigid. They promised to prepare a car that could cross into Italy, but upon arrival, they informed us that there was no suitable car. After delaying for two hours, the rental company told me I could go to Switzerland to change the car, so we had to start the trip with a Volkswagen Multivan.

No car available, received a downgraded vehicle

The day before picking up the car, we first went to the car rental point at Cologne Central Station to find the location. Maybe because it was almost closing time, the woman we met was quite indifferent and appeared to be in a hurry to leave. However, the next day, the gentleman who attended us was very friendly and courteous. The car was more upscale than I expected and included a navigation system. The man inspecting the car at the return location in Frankfurt Airport was also very friendly. Of course, we made sure the car was clean inside and out. Overall, everything was great, and the excellent car added to the enjoyment of our trip.

A very large and reputable car rental company with excellent service.
