My girlfriend and I spend 3 nights at Vienna.
The apartment located in a great location, very close to the main square and everything there.
The flat separated to few parts with 3 partners that lives in the apartment (except the host). So we shared the toilet and bathroom with them but we didn’t have any problems with that. The apartment we stayed at has a separate entrance to a large room with a nice window (to the back and quiet side of the building).
The kitchen isn’t in a good shape so if you’re planning to cook you should know this. Otherwise it more than fine.
Host was available for any questions but not always know what to do.
