The apartment is located near Wien Mitte Station - reachable in 5 min after arriving with CAT train from the airport. We walked everytime to get to the city center (20 min to Stephansplaz) and also to Belvedere palace (30 min walk). Nice coffe shops and restaurants nearby.
The apartment is located in a very safe building and is well designed, clean and cozy - we didn't have to open the heater although we visited at the end of November. The bathroom and shower are see through from the bedroom.
We really enjoyed our stay and Milena was responsive and attentive to our needs.
