Absolutely perfect location. If you're not lazy then everything is in a walking distance. The flat is large enough for 6 adults in 3 separate bedrooms. It has a kitchen, bathroom, separate toilette. Not that easy and quite pricey to park outside if you come by car, though there's a cheap P+R 2 subway stops away.
Should we need such a large apartment in Vienna again, then this will be my choice for sure.
