We rented the flat for two nights with our 19 year old daughter. Alexander and Bettina live right next door and were immediately available upon our arrival. The flat was lovely and clean. They had any travel guide of Vienna one could want including local brochures for attractions and transportation. The location was walkable to the opera house area and most anything we wanted to do in the city. The flat is also conveniently located to a tram stop which took us to most other locations that were a longer walk. There is a nice Spar around the corner which allowed us to pick up a few things to have in the apartment for cooking. We would most definitely recommend this flat to either a couple or three people traveling together. It was perfect for the three of us. It was a bonus to be able to catch up on laundry while there as well!
