There was no one there when we arrived, and the staff was very nice.

The car rental point in Vienna had a shy young guy. His English wasn't great but it's easy to understand him. If you find the door locked when you arrive, don't worry, just wait 10-15 minutes and he'll come. He might be inspecting car conditions. The service attitude is excellent. The pickup is on level -2. If you have any issues, take a photo and go upstairs to ask him. He's very patient in answering all questions.

The store at Vienna train station is easy to find. The car pick-up process is simple, without any upselling. The staff is very friendly and communicates well.

Not bad, our English isn't great, but the guy patiently explained everything and let us take photos to translate. We spent a long time understanding the car in the basement, and some passers-by even came to help explain.
