Picking up a car in Hamburg city center is not easy. There is no branch office, communication is inconvenient, and I made several international calls to the central office, which redirected me to a branch office. I waited for two hours and finally got the car in front of a Starbucks. Returning the car at Munich airport was also problematic. The branch office is far from the airport, and after returning the car, I had to wait for the branch to arrange a vehicle to take me to the airport. As I was in a hurry to catch my flight, I took a taxi to the airport, costing over 20 euros.
