This place turned out to be perfect for a couple. A full size apartment with bedroom, separate and large living room, kitchen, bathroom. The subway stop (U1 line) was 100 metres down the street. Only one stop to Karlplatz.
The host, Verena, was truly fantastic. Greeted us with wine and a snack - very much appreciated after a 30 hr trip from Australia. She was helpful throughout our stay offering useful advice on happenings in Vienna. We greatly enjoyed discussions over a glass of wine.
