We loved the apartment, it was just like in the pictures. The hosts were very helpful - Katerina was always available by e-mail and Bernd (her husband) welcomed us in the apartment, gave us a tour, provided some tips for sightseeing and shopping in Vienna. We very much enjoyed our stay in Vienna and the apartment was awesome, just what we needed - quiet, clean, with great kitchen (we usually cook our meals) and big bathroom. And they also let us use their Netflix account, so that was a very nice attribution :) Everything was great, we highly recommend this place!
