Pretty good.

The rental process was quite fast, and the car was fairly new though a bit small. However, small cars are actually very suitable given Europe's limited and narrow parking spaces.

The fuel deposit was never refunded. Additionally, I was charged again for adding a driver and for cross-border fees when returning the car, totaling 18,000 RSD. I reported this issue to the car rental platform multiple times, but never received a direct response. I hope they address this issue soon and provide a fair resolution.

Belgrade Airport branch. Arrived an hour late for an 8 AM pickup, but it wasn't an issue. The overall process was smooth. They offered me an upgrade from Polo to Golf twice for an additional fee. I politely declined, and they ended up offering a free upgrade, which I gladly accepted. When returning the car at 9 PM, the return window was closed, but there were staff available in the Europcar area of the parking lot to assist.

The weather was cold and rainy. We were asked to drag our luggage to the parking lot, but there was no car available there. We were told to wait for five minutes, but it took about twenty minutes. It was 0 degrees and raining, and after such a long wait, a car with a flat rear tire arrived. We found out and were told we had to wait another hour to change cars. It was too cold, so we dragged our luggage back to the airport to wait. The process was inefficient, and the pick-up staff were very rude with a heavy accent in English, and got impatient when asked to speak slower. We were the only ones renting a car that day, but it took a total of three hours to finally depart.
