The apartment is ideally located, walking distance from most of the sights. The rooms are spacious, good for a family. Communication was very fast and smooth with Christina, she even sent detailed information over email about connections from the airport. Billy (her associate) was there at check-in, a very nice man who suggested us restaurants nearby and it was always a pleasure to see him waving us even on the street when we later met him.
The only slight downside is that the wifi connection is poor and there is no window in the livingroom.
