We had a great stay at Christian's apartment, it's very quiet but very conveniently situated - about 5 mins walk to Stephansplatz. There are a lot of bars and restaurants around, but as it faces an inside courtyard it is very quiet. It is also very clean and stylish and has all the comforts you would want. We would happily return to the apartment (and to Vienna which we loved). Thanks for a great stay, Anthony and Ruth.
