They added unnecessary services when renting the car, charging over 100 euros extra.

Pickup and return were very convenient. It took a while to find a place to refuel at the airport, but everything else was great.

Pretty good, they even gave me a free upgrade to a Grand Cherokee. The car exchange was smooth as well.

Since there were many customers at Hertz, the wait time was quite long. However, we got a new car, around 600 kilometers driven, a Ford.

This was the worst car rental experience I've ever had. Initially, we planned to pick up and return the car at the airport, but we returned it a day early at the Frankfurt train station. We specifically asked at the counter if there would be any extra charges and if the rental fee would change. I was okay with paying a fee for returning the car at a different location. The frustrating thing was the staff at the Frankfurt train station assured us that if we returned the car a day early, they would refund one day’s rental fee to our credit card. We happily returned the car, but after we got back home, we received a bill showing an additional charge of about eleven hundred yuan for five days of rental. We tried repeatedly to communicate and appeal with Zuzuche to no avail; they required evidence of our conversation with the employee at the Frankfurt Central train station. It's ridiculous, how are we supposed to provide that after returning home??? This was an extremely frustrating car rental experience.
