You are not booking a hotel.
Your room is 24m2 big and is located in a 100 m2, high ceiling apartment with original wooden floor. It's very close to Landstraße/Wien Mitte, which is a very central station in the city and the first stop coming from the Airport. It's also a metro station (line U3 & U4) and there is also a shopping mall and restaurants. From here you can reach the city center very fast: 10 minutes foot-walk to Stephansdom, 5 Minutes to Hundertwasser museum or Danube Canal.
