We stayed 3 nights in Daniella's studio and it was awesome! Everything was very well organized, neat and clean. There are different supermarkets nearby and the kitchen is well-equipped. The flat might seem a bit far from the city center but it's very well connected through public transport (U6 Dresdner Str. and S-bahn Traisengasse). So getting around Vienna and reaching the central station was breezy. I definitely recommend Daniela's listing.
