1. We weren't informed that we needed a pass for crossing the border, only told to show relevant documents to the police if needed, resulting in a 150 Euro fine. 2. The amount charged didn't match what was told at the location, they overcharged us by more than 3500.

The waiting time in line was very short, but the staff were not very polite.

I requested a receipt from the Europcar staff when returning the car. They said they would email it to me within two hours, but I still hadn't received it after a day. I emailed them, but they didn't respond.

The store in the center of Vienna is very convenient, with car pickup in the adjacent garage, but the garage staff can be hard to find. Once the car is picked up without issues, you can leave directly. Driving was limited to Austria with a provided highway ticket. Returning the car was near Salzburg train station, which required a bit of walking, but self-service return was supported. Overall, it was satisfactory. However, the cancellation of the credit card pre-authorization took a bit long.

The wait on the counter to pick the car was very long. The lady who served us was very helpful and professional.
