I stayed here for a month. The property is totally fine for a short stay though a bit expensive for the quality. It is listed as a 2-bedroom, but there is simply a large bed filling the living room, leaving no living space except for a small sofa and desk in the hall to the back balcony. It felt a cramped, though other important things mitigated this—see below. It really just depends on what’s important to you.
All of the above was worth dealing with to me because the location can’t be beat. It was a short walk from groceries, train and bus, waterfront, and tons of wonderful restaurants and cafes as well as a fantastic yoga studio.
Another thing to note—if you are not tolerant to summer heat (it got up to 104F), this may not be the place for you. I had both fans running whenever I was in the house, and balcony doors were open, and it was still very very hot—probably just due to the location and architecture. Anyway, if you need air conditioning, look elsewhere.
Totally fine stay, loved exploring Lisbon while taking remote classes, and this neighborhood is a joy.
