I stayed at Anna's apartment for four days, attending a conference at the Schönbrunn palace. Communication was quick with Anna and she was great in organising somebody to let us into the apartment although we arrived just before midnight.
The apartment is tastefully decorated and spacious. The only smaller size was the kitchen - oh well, here only one can be cook at the same time :-)
There is a supermarket just round the corner, some other shops close by as well as restaurants, a medium large park, the technical museum and of course Schönbrunn palace. Halfway down to the palace is the metro station, so getting to town is no problem.
Great place to stay while visiting Vienna!
