It's an appartement in a good location, quiet and with quick access to bus and metro.
You have one bus line (742) at 2mn by feet and metro 20mn by feet. You can easily take the bus and take the metro after in order to go to the center of Lisbon.
The flat is great, on 2 floors, with 2 rooms (1 double-place bed and one other bed) and a sofa where you can sleep. A large kitchen, 2 bathrooms, 2 toilets...and its proper. No clim but Ventilators if you really need.
Good communication with Isabel who answers quickly and who is really kind.
You also have a supermarket next door and chinese restaurant.
No problem during the stay.
Enjoy !
