In my view this is an ideal place to stay for a couple or a solo traveler coming to Vienna for sightseeing. The location is perfect! All the top sights, Opera house, Jazzland, the most interesting neighborhoods, great restaurants and cafe are at walking distance, except for Schoenbrunn Palace which is accessible by a short Underground ride. The Underground and tram stations are two steps from the house. The apartment is small but cozy and well equipped. In spite of the central location, it is quiet in the apartment if you close the windows in the night - we slept very well.
Bryan is extremely hospitable and welcoming person! When we arrived he not only gave us usual explanations about the apartment but also showed us the neighborhood and gave us useful tips about the shops and restaurants close to the house.
We enjoyed our 5 days stay at Bryan's place very much and highly recommend this place to others.
