Diana's apartment is excellent - as pictured, particularly the bathroom. Building is secure, apartment is spacious and check-in/out was very easy. The apartment is outside the ringstrasse by a short walk, but due to the cold we found it a little far out from the main part of town, in summer the distance would be negligible. Wifi and other amentities were all excellent, except for the pillows which were flat/lumpy. Overall we enjoyed our stay and would stay here again next time.
