We very much enjoyed our stay at Elisabeth's apartment. It's in a great location where we could walk to major tourist sites and public transportation was 2 blocks away.
We also enjoyed the coffee shop on the corner every morning. The apartment wasn't fancy but was clean, comfortable and had everything we needed. Elisabeth was very helpful, friendly and accomodating. When we couldn't figure out how to run the washing machine, she came right over and took care of it for us. We would recommend this as a comfortable, reasonably priced place to stay in Vienna!
