The flat is in a great location. We walked to almost all of the galleries and museums etc. we wanted to visit. The flat is light and bright, quiet and with a wonderful roof terrace we enjoyed in the summer heat. The shower was great, the bed very comfortable. We didn't meet the host, but he responded promptly to an email when we had a query. Very close to public transport links. All in all a great place to stay in a safe, central neighbourhood in Vienna.
