We had a good stay in this flat. The kitchen is very workable. The double bed is comfortable with good sheets, pillows and comforters. The south windows give lots of light. There is enough storage for unpacking your clothes, computers and so on.
It was perfectly located for accessing the SBahn station at Rennweg and local transit like the 4A bus and the 71 tram. There are grocery stores and pharmacies in walking distance. There are good restaurants nearby that have Viennese eating in them (not just tourists).
