We loved staying at Wolfgang's apartment. It was large, bright, and nicely decorated with good bathroom, beds, washing machine, etc. Folks who are not fit should note that there are about 70 steps up to the third floor - hardly noticed the climb by the end of our week. The location is fabulous: quiet with good amenities nearby (Spar, hardware store, cafes, Thai food, etc). We enjoyed visiting the Hundertwasser buildings nearby and had easy access to the rest of the city from tram stops for the 1, 2 and O lines within a block or two. Highly recommended!
