The wait times for picking up and returning the car were very short, almost no waiting. The staff were very friendly and patient, even if they weren't fluent in English.

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 in Serbia were quite nice.

Overall service is fine, but the car is only available at the scheduled time.

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.
