We had a friendly welcome by Silvia's mother who made herself available to give us the keys of the apartment when we arrived in Lisbon. The apartment was very well: clean, tidy, practical, offering enough space for 5 people, with a well equipped kitchen and a large bathroom. One point to mention: the beds were large but a little bit hard and the bedroom giving on the street was noisy, especially because of planes approaching the airport.
The location is quite close to the city center and the neighbourhood is very quiet. It's well deserved by buses but you can also walk from Marques de Pombal, it's only 15 minutes.
We had a very nice stay and we would recommend this apartment. It has a very good price-quality ratio!
