Really nice studio apt very centrally located. If you are willing and able to walk up and down 4 flights of stairs - this is a perfect place to stay for 1 or 2. Don't be deceived by the dark and seemingly old entrance and corridors - the apt is sunny, modern - very nice bathroom and kitchen. Double thick french windows keep street noise out. Tram across the street. Metro/subway 5 min walk. I would definitely stay here again if/when I visit Vienna.
