We were two families staying for one night only on our way back after two weeks in Portugal including a week at another Airbnb in Lisbon. By comparison the apartment was just an OK place.
Every bedroom has a bed and and a closet. The common area has a TV, a coffee table, and a sofa, which doubles for a bed if your group has more than 7.
The apartment large apartment, which is great, but I wouldn't want to spend more than one or two nights there. It feels empty and worn out.
