My boyfriend and I stayed here for a week. The location is perfect, a really lovely area with lots of nice restaurants and bars within minutes plus an easy walk to the other popular spots. The apartment was spacious, quiet and well equipped.
It is at the top of a big hill and up a few flights of stairs which was no problem at all for us but might be a consideration for older guests.
Some days were very hot days while we were there and the apartment was very warm even with all the shutters closed. There were two fans and we moved them both into the bedroom at night which was a big help and when the weather cooled down, we got used to the apartment's temperature.
A very comfortable and spacious apartment for exploring Lisbon.
