This was an amazing location for what we needed during our 4-night stay in Lisbon. Super walkable to everything and the bldg itself was quiet despite being on a busy street. Maria + team were kind enough to let us leave our bags in the apt earlier as we wandered the area a bit. The apt is bright and airy, and clean and having an elevator in the bldg was also a plus for our luggage.
Like others mentioned the ceilings are sloped, but I'm 5' 7" and managed fine on the 1st floor without issues. The 2nd floor is def more precarious for anyone over 5' 3" but manageable. The only issue is the slow-draining showers in both bathrooms—likely fixable if they could de-clog the drains. Otherwise, I'd recommend this staying here if you want a great location.
