A perfect spot for visiting Vienna. Everywhere in the central area is easily accessible on foot, and if you're weary after a day's walking, the U-Bahn is only a few steps away. You wouldn't want to cook a gourmet dinner for 4 here, but everything is more than adequate for simple self-catering, and who wants to eat at home when you're in Vienna anyway? Try Balthasar right by the Nestroyplatz U-Bahn for superb coffee.
Cristina was very helpful with small problems although our paths never crossed.
