Rather big place (for lisbon I think) in a very convenient location, not too many stairs for an average fit person. Safe area (at least for men), some small bistro and grocery around. Very close to metro, tram 28 and graca (recommended for brunch etc).
Quite neighborhood (at least during covid), occasionally you can hear the neighbors through the thin walls, but I was surprised how quite the whole city is.
Small bathroom but ok, fridge a bit noisy at night. Skylights for fresh air are a nice add on.
Host let me check in early, check out late and follows hygiene rules!
I extended my stay, since I postponed my flight and this place is definitely good value for the price (again: during covid..)
