Motti and Annemarie have a perfectly located studio in Vienna. It is just outside of the tourist area, but is a 3 minute walk to "the ring" of the old city. They have converted a pretty large room into a very functional studio apartment space with a sleeping loft and it is quite comfortable. The space is a bit small for 4 adults, as we were. You are essentially sharing one big room - but since we spent most of our time touring the city it didn't matter. We would stay again.
