From Germany to Czech Republic, then to Austria, Switzerland, and back to Germany - a perfect four-c

The rental staff were very polite and had a good service attitude.

Sometimes the queue at the counter is very long, sometimes it's completely empty. It depends on the time; on average, the wait is 10 to 20 minutes. The service attitude is alright; some are very business-like, and some are more eager to help. Encountering a good employee is a matter of luck.

The deposit was withheld without explanation. I only realized it several hours later when I received a text message. When I asked about it while returning the car, they finally provided an explanation. The wait time was very long, it seems their business is too good.

Pretty good, simple procedures, but a lot of things need to be done by yourself.

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