About the location (from Wiki):
Schwarzenbergplatz is a Vienese square in Vienna, Austria. It is actually more a like a small, open street than a square, and it runs between the Kärntner Ring section of the Ringstraße and Lothringerstraße. Travelling south, the street, Schwarzenbergstraße, becomes Schwarzenbergplatz after passing Kärntner Ring. Schwarzenbergplatz then continues briefly until it becomes Rennweg Straße as it passes by the large enclosed parks of Belvedere-Garten and the Palais Schwarzenberg and the Schwarzenberggarten to the west.
