We met Wolf at the apartment where he gave us a very thorough orientation along with apple strudel and Prosecco. The apartment has a lift which is really nice given that the apartment is on the top floor. The location of the apartment couldn’t be better and is right around the corner from St Stephan’s Cathedral and the subway. The apartment was large with a separate dining room and a comfortable living room. They were a couple fans which really helped on hot days. It was quiet even with the windows open. The bedroom had a closet to hang clothes and the bed was comfortable. There was not much room in the shower because of a sloping wall, but otherwise the bathroom was fine. The kitchen was small, but functional and had a dishwasher which was nice. Note that there is no oven or microwave which seems to be common in the area. There was also a washer/dryer combo so you can do laundry if needed. We would stay here again next time we are in Vienna.
