Christoph was a very responsive host, letting us extend our stay at the last minute. The flat is very nice, spacious and solid with a nice terrace and comfortable sofa. Neighborhood is good as well, with cafes and restaurants close by, as well as a Spar and the huge Mariahilfer shopping street. Cafe Jelinek, just around the corner, is especially nice. If you are travelling with young children there is also a good playground just around the corner.
