The service was extremely poor. They forced me to purchase full insurance and made various unjustified deductions after the rental period. Even two months later, deductions were still being made, and they did not respond to emails for communication.

The usual routine of upselling insurance during pickup. This rental company charged me 29 euros for car cleaning—should have cleaned it myself for 2 euros. Small rental companies rely on these charges to make money. However, they were quite friendly.

Very disappointing! After returning the car, my credit card was charged over 200 euros, claiming it was for car washing and some Vienna-related fees. During the return process, they confirmed there were no issues, yet the next day, they deducted money. They rented me a car with a Hungarian plate and still charged me a fee for entering Vienna?
The car itself had issues with the fuel gauge. It showed the tank wasn't full even after filling up and the pump automatically stopped. I ended up going to three or four different stations to refuel. Only when returning the car did they mention the fuel gauge was faulty. Couldn't they have informed me beforehand?
This was my worst experience in over ten self-driving trips in Europe.

Very satisfied.

It's okay, but Austrians speaking English are quite hard to understand.
