Spent 2 nights here to visit vienna. This room is one of the bst deals you can get, just 15 minutes away from the city by foot, but also 5 minutes away from metro stop for lazy ones.
The house is located in a peaceful neighborhood and palace. The only other person in the flat was very friendly and also silent, we barely noticed his presence.
The room is very large and warm, so that austrian cold won't get you even in winter, but not that clean. Kitchen os fully equipped for everything you could, but it was also not so clean as well. Bathroom was nice and clean.
Host was very helpful and replied quickly most of the times.
Overall, would highly recommend for a cheap staying in the city!
