Amazing place, dead center in the tourist hotspot of Lisbon. The appartment is super clean (we even received a cleaning mid-stay), very good amenities, especially the kitchen which had everything, a pretty big bed and easy communication with the host!
We were 4 adult people, two in the bedroom and two on the sofa bed. It worked, but the sofa bed is probably more suited for one kid and one teenager, as one bed was quite small. Other than that I would recommend the appartment to anyone!
