This trip was arranged based on your company's promotion of visa-free travel and low costs in Serbia and Bosnia and Herzegovina. We booked a car through your platform, which turned out to be the biggest expense of the trip. We expected that this expense would bring a pleasant experience, but it turned into a headache throughout the journey. We were a group of six and ordered a 7-seater car, but we were given a 5-seater. The staff at the pickup location promised we could switch to a 7-seater the next day. Considering it was already 11 PM when we picked up the car, we decided to take it for the night. However, we were told the next day that we could only switch cars four days later. Our subsequent travel plans included accommodations in Bosnia and Herzegovina, so we couldn't stay in Belgrade for that long. We had to make do with the car, which meant four people cramped in the three seats in the back, causing discomfort and even motion sickness for one of us. When driving out of Serbia, the border police noticed the overloading and held our passports for over an hour. On the way from Mostar to Sarajevo in Bosnia and Herzegovina, we were stopped by police and fined 100 euros for overloading; the officer said the fine was supposed to be 200 euros, so he didn't issue a receipt. We were constantly worried about being fined again for overloading, but fortunately, we weren't stopped at other checkpoints.

1. The counter staff was not particularly friendly and seemed somewhat arrogant towards Chinese tourists, possibly due to previous negative experiences with other tourists. 2. The return inspection was extremely thorough, with three rounds outside, three rounds inside, using hands and lights, but no damage was found. Possibly because: firstly, we took great care during use, avoiding bumps; secondly, we spent around 1000 local currency (about 60 RMB) to clean the car before returning it; thirdly, the car was not cleaned when we picked it up, it even had bird droppings, and the staff wanted to return it based on the previously marked damage list, but we insisted on rechecking and found at least three traces, which we recorded to avoid issues during return. 3. Conflicts arise from cultural differences, but mutual understanding is key, even with overseas car rentals. We respect others, and they will respect us. I personally think that those who don't purchase full insurance are checked more thoroughly because, in the logic of the locals: 'If you don't buy full insurance and there's hidden damage, how can I know? Therefore, I must be more meticulous in my inspection.' This is understandable and possibly due to previous distrust caused by dishonest renters.

The staff's attitude was average. We had to drive to the company to get the green book for crossing the border. Why couldn't we get it at the airport rental location?

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 staff at the outdoor pick-up location seemed a bit inattentive. During my first pick-up, they forgot to give me the vehicle registration. When I returned to the airport, they claimed I lost it and asked me to pay a 186 euro fee for the loss. As it was impossible to determine who was at fault, I had to pay the fee. They then gave me a replacement car and claimed they had already given me the keys, but later I found out the keys were still with the same staff member. Overall, the staff at the pick-up location were subpar, making it an unpleasant car rental experience.
