Cozy apartment in a lovely residential area! Even though the apartment is small, it is smartly divided into different spaces, giving the feeling of more roominess. Dada was very communicative and the check-in was smooth (Dada was unable to greet us because we arrived on Orthodox Easter, but he arranged for the housekeeper to meet us and give us the keys). The U station (red line) is right down the street and because of the central location, it is easy to get to all the sights of Vienna (although it's just a 10 minute walk to Haus der Musik and another 10 from there to Stephansdom). Dada gave us great restaurant recommendations (in fact, this area had a number of highly rated upscale restaurants) and other suggestions for what to see around the area.
