I stayed here for a month and quickly became friends with Werner. He's a very thoughtful host, knows a lot about Vienna and was a great buddy during the covid outbreak which started at the time. The place feels very comfortable, always well kept and clean. It's located near the city center with a good connection to the train station. It has a lot of history behind (which can spark some very interesting conversations). The room is quiet and cozy, which makes for a great sleep. Overall, I really enjoyed my stay and would definitely come back.
