Munich to Geneva

They canceled my reservation without prior notice, forcing me to rent a car for 240 EUR at the last minute

This rental company specifically scams Chinese customers. They pre-mark the wheel hub and then claim you damaged it when you return the car. How could it possibly get damaged there? German brains must be full of crap. They don't allow you to inspect the car when picking it up, and when returning it, they say everything is fine. Four months later, they deduct your money, truly shameless.

It was okay, but the selection of car models is limited. There was no on-site confirmation when returning the car.

Pickup was very convenient, but returning the car was confusing. The drop-off location was inside a multi-story garage with no visible counter. We had a hard time finding an attendant to return the car, and the next day received a call saying the car wasn't returned. Seems like there was a communication mishap.

The rental office is near the train station, but there's another one close by, which could be confusing. However, it wasn't a big issue.
