The flat was great and exactly as pictured, I actually was quite overwhelmed by the enormity of the room. Everyone was very friendly and welcoming into the flat too. Klaus provided me with details on how to arrive and even offered to pick me up, plus he provided me with a few local restaurant recommendations around the neighborhood. Close enough to all the sights, yet far enough to avoid tourists in the neighborhood. Lots of cool camera shops on the street the flat is on too if you're a photog. I would definitely stay again in the flat if I found myself in Wien.
