The confirmed car model was not provided in the store. Even after contacting the rental company, we were still downgraded. The cross-border fee was less than 30 euros, but the tax was as high as about 12 euros; the tax accounted for nearly 50%.

Renting a car was quick and convenient, returning the car was hassle-free, and the service was excellent!

There was no 7-seater Mercedes van at the Hertz location in Frankfurt Airport, they gave me a Ford instead. When I wanted to switch, the staff said it was the only option, and it was diesel. Very frustrating. The staff was enthusiastic, but it felt fake. They pushed for full insurance, about 40 euros per day. When I went to pick up the car, the man there was really irresponsible, just reading an e-book and not helping me find a child seat. When I found out there was no child seat in the car, I went back to him and he finally got one for me. He asked if I wanted a booster seat, and I thought, I paid an extra 55 euros and this is what I get? In the end, I chose a child seat for ages 3-12 (not an ISOFIX one, just secured with a seatbelt).

There is a service point right at the airport, the procedure is simple and fast. Although the vehicle was upgraded, there was no choice available, you have to accept whatever car they give you.

The store is quite easy to find.
