Stayed there for a month and everything was perfect. The apartment is big, with 2 floors, nice decoration, very clean, safe, sunny and very quiet. It has everything you will possibly need( even a piano) and then more...Rosemarie was kind enough to have even supplies of various kitchen staples like coffee, tea and many other things. The location of the apartment is excellent; right next door there is a big supermarket, the tram is 3 minutes walk and gets you right at the center of city. A subway station is also close that gives you access to every part of the city. So based on where you want to go you can use the tram, subway or a combination. Rosemarie and her husband were excellent hosts, always there when something was needed. In general, I think this is one of the best deals in Vienna, especially for longer stays. I would definitely stay there next time I visit Vienna and would recommend it to everybody.
