Ulrike's apartment is one of a kind. As other reviews have remarked it is stylish, spacious with high ceilings and white walls and has beautiful chairs and art works. And if you want an authentic Viennese experience, stay here: the building is indeed classic with lots of stairs, a central courtyard, double windows (it's very quiet) and vines clinging to the walls outside. It also has everything you need for a comfortable stay: a small, but lovely bathroom with shower, functional kitchen with dish and clothes washers, and a good bedroom with storage space. Ulrike is also a great host - she supplied prompt responses and thoughtful comments. The location in Neubau is relatively quiet, but within walking distance of the centre . . . which we mostly chose rather than using public transport.
