Christiana's apartment was more than great. Spotless clean, has more than everything inside, great heating and a beautiful building. The area is hip and quiet with lots of stores and restaurants around. Very close to both transportation (U-Bahn and Tram). Also very easy to walk to the city center. The check-in process is easy and practial. We also had a chance to meet Christiana during our check out and she was extremely lovely and helful. This is absolutely the place to stay in Vienna, look no further.
