A small apartment facing the courtyard of the building with enough amount of daylight during hot summer days in the city. 10-15 minutes with city transport til downtown area. The beautiful Danube reachable by foot. Near some of the traditional Viennese restaurants. All in all nice neighborhood and quiet atmosphere if you want to escape city bustle.
If you reserve the flat during fall, winter, and spring you will be sharing space with me but I assure you that I'm one very cool roommate ;)
