The apartment is great - large, bright, clean, well-equipped, comfy, and of course, the best part: a wonderful roof terrasse. Ideal even during the recent heat wave :-) The area is quiet, but with lots of small cafes and shops, a supermarket around the corner, public transport. Mariahilfer Strasse (main shopping area) is five minutes, Westbahnhof maybe 15 minutes walking. Christoph was a wonderful host, helpful with all requests and questions we had.
