From Frankfurt to Hamburg to Denmark and back to Frankfurt (Various Surrounding Cities)

Very good

They force you to buy additional insurance, otherwise they won't allow you to cross the border. The crossing fee is only 25 EUR, but the insurance costs 66 EUR plus tax, which altogether cost an extra 120 EUR. I booked a C-class but got an X1 instead, which is clearly not the same class in China. Maybe in Germany, X1 has the same price as C-class. I've had a good impression of Hertz before, but this experience was very disappointing. The staff refused to mediate over the phone with the booking agency. It was really frustrating. If I weren't in a hurry, I would've canceled the rental. Do not choose this company.

Very satisfied

Hertz's service in Europe is also quite good. I used Hertz when I traveled to the US as well—picking up and returning the car was very convenient.

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.
