We have spent there 4 nights. Everthing was perfect. 5 minutes to the nearest U Bahn and tram station. Cosy and comfortable flat with fully equiped kitchen. As other visitors we enjoyed their collection of mainly classical music CD´s. Although we did not meet Nora and Andrej as they travelled abroad, Nora´s father gave us a key from the flat and showed us personally all necessary.
I recommend to all future visitors to live in their flat. You will surely be satisfied with your stay.
