Pretty good. They gave us a nearly new car with just over 4000 kilometers. However, it did not have a reversing camera. During the trip, we encountered a low oil level and had to add a liter of oil in Greece.

The staff efficiency was quite good. The only strange point was they only accepted that shabby little booklet translation and didn't recognize other forms.

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.

1. They ignore you if you don't speak English, even with a reservation. 2. They forcefully upsell insurance, not allowing you to see the contract until you sign and pay, which they use to justify the insurance push.
