Our stay at the flat was excellent. The host made it really easy for check in and check out and was very hospitable, having prepared the flat with everything that was necessary. The flat is as shown in pictures, very high ceilings in Viennese style, great light coming in through ample windows and quality materials (floor, doors). The neighborhood is very central, has an east London type of vibe but also walking distance from Karl's Platz and the older part of town.
