I loved staying at Astrid' place - it was beautiful, quiet, stylish and just what i wanted on my short stay in Vienna. Astrid's flat is is a walking distance from Karlplatz and all the major attractions, including the Museum Quarter, Secession, Stephanplatz, etc. There are plenty of cafes and grocery stores in the area, but practically no tourists, which makes for a more authentic Viennese experience. Astrid is a perfect host, i regret not having a chance to talk with her more as we both were out most of the time, but i would def. recommend her place to anyone visiting Vienna!
