Rosemarie and Franz have been great hosts. My friend and I stayed at the apartment for a month, and it has been a very pleasant experience. It is a lot bigger than it looks in the pictures. The Kitchen has everything you need for preparing meals, there is a washing machine in the bathroom and the hosts provide you with towels which are replaced once a week, as well as clean bed sheets. The living room and the bedroom are very bright and the walls are decorated with lovely paintings painted by Rosemarie. There is also an FM radio in the living room. The lower level stays very cool even during warm summer days. The neighborhood is safe, there is a small park not too far away. The apartment is well connected to the public transport, its just one streetcar station away from the nearest metro station. The grocery store is right next door. I would definitely recommend staying here in case you are visiting Vienna, and would love to stay here myself the next time I travel there.
