Don't hesitate on this one. Finally a concise review of Stefan's place. I traveled alone to Wien as a woman. I stayed for a week so I have a good idea about the place. This apartment was ideal. Firstly, the location was superb. The U3 (green line) Pilgramgasse station and close by buses provide a means to get anywhere you need to go. I got to every possible tourist spot in 30min or less. There are restaurants, two Ankers (bakeries), cafes, a DM, and a Billa (grocery store) around the neighborhood. It's so convenient to walk. I never felt unsafe even at night. Secondly, the comfort of the apartment is great. The apartment was so clean that I could not even find dust on the artificial plants. I am picky about beds and the bed was very comfortable. The sheets and duvet were clean and soft. The Wifi was fast and consistent. Stefan has so many little extras that make life easier (i.e. extra hangers, laundry dryhanger, extra soap, shoe horn, umbrella, etc) The shower was relaxing after a long day walking in museums. It had consistent hot water. The kitchen was adorable and suited my needs. Thirdly, Stefan was a good host. Before I came I received lots of information including a photo tutorial as to how to get checked in. I felt like he cared. He left some yummy Mozart Kugel for me. When I had an issue with something that broke, he addressed it with a great attitude. Trust me I will be back in Vienna and I will try to get this condo if it's available. Please keep in mind that the building is old and there will be some squeaky floors or sounds from neighbors from time to time. It was not a big deal. Austrian water quality is so good so you can drink good water from the tap. Your skin and hair and clothes are softer due to the water. Also I don't think that more than 4 people could stay comfortably in the apartment. Keep in mind that many Europeans use line dried towels so they are rougher than what most Americans are used to. Moreover the "ground floor" to most Europeans in really the first floor to folks in the U.S.. I walked a small flight of stairs to the apartment everyday and had no issues at all even with luggage and groceries.
