Everything perfect! Above expectation... Extremely quiet, large livingroom and kitchen, rooftop with terrace, well equipped, great great location in a very quiet street (5 mns walk to Musikverein and Konzerthaus, less than 10mns to Staatsoper, even less if in a hurry...). Christoph gave us all needed information and we were confident that he would answer any pb quickly and efficiently (hopefully, this was not the case...). We highly recommend this flat.
