I highly recommend staying with Motti and Annemarie! I spent four nights at their lovely, private apartment and it was just what I needed. Just a short walk away from public transportation and a 15 minute walk to the sights and delights of Vienna. Super convenient to a lot! I came for a research trip and to see the museums, traveling by myself via train from Germany. When leaving, I caught a bus to the airport that departs every 30 minutes and it was a breeze -- a 5 minute walk away. I appreciated the kitchen and roominess of having an upstairs sleeping room separate from the living area. The light was beautiful during the day and the airiness of the place is accentuated by the high ceilings. I would definitely stay here again. My only regret is that I didn't have more time to check out the cafes and eateries that were on the opposite direction of the museums -- really just the other side of the block but they looked great. Not enough time in Vienna, but when I come back I know where to stay! They were very communicative and responsive to all my questions, making them excellent hosts.
