your personal ideal route, you can use http://www.map24.at.
Entering
Vienna on the A4 (motorway from direction Bratislava, Vienna International
Airport):
Leave
the A4 in direction "Zentrum, Prater", follow Schüttelstraße,
Untere Donaustraße, Obere Donaustraße straight
ahead. Turn left crossing Roßauer Brücke (bridge over Danube
channel), following Türkenstraße and Hörlstraße
straight until you reach Währinger Straße. After crossing
Währinger Straße (the road turns slightly left into Rooseveltplatz)
you see a church ("Votivkirche" - that's NOT St. Stephan's
cathedral!) on the right-hand-side. Turn right into Universitätsstraße,
further the 2nd right into Garnisongasse and the 2nd left into
Schwarzspanierstraße. Go on straight ahead to Otto-Wagner-Platz
or better find a parking place ;)
