The place is the same as in the photos, except it is even more spacious than it looks like in the photos. Two of us stayed in the room for 4 days, and we had great time! Yusuf is very nice and polite, it was easy to talk to him. We arrived a bit later than planned and the check in was smooth-he was waiting for us. The room is in the one part of the flat, and Yusuf's room is in the other, so we had our privacy. Also, kitchen and bathroom are next to the room. Yusuf even explained us where to park our car so that we do not have to pay (thanks so much for this, Yusuf!)
We didn't try to reach the city centre by foot, but the tram is 5 minutes walk from Yusuf's place, and U-bahn is 8-10min walk (once you reach the U-bahn station, it takes 5 minutes to reach Karlsplatz). The huge supermarket is right across the street. We enjoyed our stay, and we would recommend it!
