Perfect experience - great location, pretty much walking distance to all major sites in central Vienna, with public transit nearby and a taxi stand around the corner. Apartment was clean, easy to access with self check-in and elevator, had WiFi and was very quiet at night since windows face an interior courtyard. Lots of restaurants / cafes within a few blocks. We were 3 adults and 1 toddler - just the right amount of sleeping space. Loved our stay!
