Satisfied, no pushy insurance sales. Although the car had over 100,000 kilometers, it was in good condition. Didn't have time to wash the car, but surprisingly no deposit was deducted.

The staff at the Serbia airport location were very friendly.

There was a watermark on the passenger seat, which they claimed was caused by us. Before taking the car, we only took photos of the exterior due to our trust in the rental platform and did not photograph the interior. I believe many people wouldn't think to photograph the interior. When we returned the car, we randomly asked a few other customers, and none of them had photographed the interior either. We didn't know about the watermark until the return inspection. If we had caused it, we would have dealt with it before returning the car. Since we didn't photograph the interior before renting (and the rental company also had no evidence that the watermark wasn't already there), we were charged 90 euros. Initially, an employee asked for 140 euros, but after arguing, another person reduced it to 90 euros. As we were rushing to catch a flight, we had no choice but to pay.

The staff was very responsible and waited for us as agreed until 1 AM.

Couldn't find the address. When abroad, we need to contact the car rental company immediately, not waste time looking for it ourselves. It wastes money and time if we can't find it. Customer service is terrible.
