Claudia was an extremely good host. There was good and prompt communication, and there was friendly chat about the day/about Vienna at the common area or kitchen. She was also accommodating by allowing me to leave my small luggage at her place while i walked around on the last day. The room was very clean, had sufficient hangers and wardrobe space. The table and chair were also clean and big. The location is a 25-30mins walk from the stephanplatz, with 2 supermarkets directly below the apartment. The tram was not far as well. Overall a very convenient place!
