Stefan's instructions on getting into the apartment were very clear, even though he was unable to meet us in person. Later, he was able to come and show us how to operate an ingenious hotplate that operates by induction. We had no problem after that. The studio apartment is very classy, with top-of-the line furnishings, which belied the less-than classy apartment building off Mariahilfer Strasse that it's in. But the building couldn't be better located to walk to everything you might want to see in Vienna, starting with Wien's efficient subway system. Mariahilfer Strasse itself is famous for its shops. We thoroughly enjoyed our stay and highly recommend this apartment.
