Antonio's flat was a nice place to stay in Vienna. Lovely neighborhood and a spacious, clean apartment with a nice kitchen. His correspondence with us was prompt, and picking up the keys at the appointed time proved easy. Our only complaint was that the apartment did not include a pull-out couch as advertised, which made it uncomfortable to sleep four people. (There were two couches that did not pull out, but one of them was a bit short for a full-sized person.) If you are traveling in a group of two or three though, Antonio's place would be great.
