For us, the location was very good. A 10 minute walk to the subway and to dining places.
The room was located in a quiet neighbourhood. It is decorated very freshly and modern. The place was very clean.
The building has a sign on the front that says that in this building in 1941 Jewish people were taken away and deported by nazis. This is common in Vienna, I saw this on a lot of places.
A good, comfortable accomodation!
