In the old town, the cathedral of St.Stephan is also very beautiful. Actually the whole area downtown is holding so many historical buildings...that it would be a must to do a walking tour (forget about driving).
Outside the city center, towards east, you may have a glimpse of the old Danube river, the Prater (old entertainment place) and the very ugly 'international organizations area' with absolutely 'discusting' skyscrapers.
