The lovely flat is very centrally located in a historical building. The Hofburg Palace, St. Stephan Catholic, ...supermarket are within walking distance. Lots of restaurants are around. The host Ursula is the nicest I have ever met, who picked us up at the airport bus station, let us check in very early in the morning as the flat was not occupied the day before, show us veggie restaurants on the way home, and introduce the city...We had a wonderful time in Vienna and in her flat.
