great place - we had plenty of space for a family of 2 adults + 2 children, sleeping on the top floor and eating and relaxing on the bottom floor. it had everything we needed. the location was also good for us - with a supermarket downstairs, the subway around the corner, and some restaurants nearby (we especially loved Mochi - really great in the evening). it's also a 5-minute walk from the Prater luna-park which we chose to end our trip (the kids loved it). and the piece de resistance - it has airconditioning so on a warm August evening you can lie in bed and cool down. check in was a breeze too, and communication with Michael was swift and to the point. thumb up from us.
