This appartment is totally unsuitable as a shared living space. The location was great, the hosts the same and the room was fine, even though a bit small.
however, for some reason there was a small window between the main bathroom and our room, which meant that everytime the other renters used the bathroom during the night, it waked us up. Also for some reason the door to the hallway was half-part glass, which meant that it was impossible to get a dark room, if the light was on. The first night the bathroom was "active" for more than two hours between 2230 and somewhere past midnight. this is not a critique of the other guests, since they probably didnt know about the light and noise issue in our room.
I am sure the appartment as a whole would be amazing to rent for your stay in Lisbon, but the small room is not recommendable if there is other renters in the flat.
In general i feel bad writing this review. a lot of things about the appartment was really great, but the noise and light issue especially in the night took a lot away from the stay.
Oh, and besides. a lot of sketchy people trying to sell people drugs are hanging out in the area just outside the appartement, but i understand this is a general issue in Lisbon
