Me and my family had a very positive experience staying in this apartment! Waking up in the huge comfortable bed, listening to the music via WiFi, drinking coffee on the balcony with a view to the quiet inner yard and then reaching the main Vienna sightseeings in less than 10 walking minutes was just great! Stefan is a good host who gave us a description how to get to the apartment in advance and then the information about the main attractions of the city (with links and arrivals).
