Harry's apartment in Vienna was wonderful. Functionally the space was precisely as advertised. Clean, working kitchen, etc. Additionally, I think both the location and building make the space very special.
The building is located right next to a self-service bike rental station (Citibike Wien). This is very helpful as one of Vienna's most expansive and beautiful bicycle parks is only a few blocks away. The city center is also relatively close (only a 10 minute walk for me and my wife). The building itself is a beautiful old Viennese apartment building which has been well renovated and is very comfortable. The AirBNB space was large, open, and clean. It's is on the top floor of the buliding and numerous broad windows give one an excellent view of the rooftops of Vienna.
Overall excellent apartment, would stay there again.
