The ground premise for my Vienna trip was primarily a condensed work trip, where I needed a place with good, fast internet connectivity for work outside office hours. Besides that I was looking for a nice, central apartment with simpler cooking possibilities, suitable for a two-week stay.
Michael's place delivered full satisfaction on my basic requirements.
The location is excellent with walking distance to the central parts of Vienna. A U-Bahn station is also within a couple of minutes walk. There are a variety of grocery stores and restaurants in the neighbourhood.
The self-checkin worked great and all communications with Michael was non-complicated and he gave a very friendly and helpful impression.
To sum up, I would like to recommend this apartment as well as Michael, and will seriously consider a second stay, if I go back to Vienna.
