This was a comfortable stay and a great introduction to Vienna. We spent almost a week here and felt right at home in a clean space. It is a complete apartment with a separate living room, though we found ourselves mostly in the kitchen area, which has a large table and a huge skylight. The apartment is on the top floor of a three-flight walk-up and is itself a duplex with a set of narrow stairs, which could be harrowing for some people. During the summer, even given the skylights, it's probably as climate-controlled as you could get without AC.
