Lovely flat in fantastic location. Vey clean and spacious and well equipped, in beautiful building, in easy walking distance to all central sights, the opera house is only 5 min walk, Stephansdom less than 10 min walk and very easy to find. Despite central location it is quiet, and the air-condition was wonderful on a very hot weekend. Host has provided lots of useful information and is very responsive. I would definitely stay there again.
