It is a great place, well located in Lisbon, near Camões Square. Ricardo and Sulamita are incredible hosts, always available and helpful.
The apartment is very comfortable, very well equipped and clean.
The few points that I would highlight is that it is in the 3rd floor and did not have an elevator and also that the street is very narrow, making it a little difficult to arrive and departure with the luggage. For us it wasnt a problem, but keep in mind if you have difficult to carry your luggage upstairs, it can be a problem.
