Right from entering the apartment I felt instantly welcomed. Although Karl wasn't there at the time the roommates in this flat where all equally warm and inviting. The room is only a short walk a U-Bahn station and only 2 stop from Stephansplatz the city center. The room was nice and cozy. The bed was comfortable and the rest of the space is clean and roomy. When I did see Karl he was very warm, friendly and helpful. I would recommend this place
