We stayed there for two nights with family (4 people). Everything was great starting with the communication, reception by our host Chiho and actual stay at the appartement. It has a fantastic view on the castle. Very central location. Almost all "must see" sights are within walking distance. The close by place Martim Moniz is a "lively place" - great to enjoy the vivid atmosphere of Lisbon (unless you want to go to bed early).
