We had a wonderful time staying at this flat. The location is great, just a 10-15 minute walk to lots of the sights such as the Staatoper, Kunsthistorischemuseum etc, but the street is nice and quiet. The flat was beautifully decorated and had great amenities (coffee machine etc) and our host kindly allowed us to check in early and check in late which was really helpful. All in all a great place to stay and I'd definitely recommend it.
