It’s a nice place to stay, and also the location it’s great. Kati it’s a nice and helpful host.
Be careful what parking lot do you choose, in some of them you need to take out the car after 24 hours, and re-enter the parking. We stayed 2 days and didn’t know that. Unfortunately the instructions below were written in german only. We paid 4 € for the first day, and additional 4€/hour for the second day. Beside that Vienna it’s beautiful and in the winter there it’s all magic about this city. We’re definitely coming back.
