Wonderful apartment as design, comfort, location and everything-we loved it! You have the subway station in a 3-4 min.walk, the opera house in around 20-30 minute walk, Mariahilferstraße and Neubaugasse are 10 minutes away, you have great places for a eating very close to the building. Airport connection is also great. Anita and Manfred are very accurate and friendly!
Really can't think of a better place to stay in Vienna!
