We were a family of three adults (there is enough space for 4) and it was absolutly perfect for us. The place is very easy to find and access, in a quiet location and it has a metro station (U1) right next to the front door. Praterstern station (with S7 from the airport) is 10 minutes walking away. There are 2 supermarkets near (3minutes walk). It was warm, cosy and nice. The building has an elevator and there is a space at ground level where you can smoke (if needed). We had a wonderfull experience. Thank you :)
