I read the reviews, but thought one night would not be that bad. Hot day, no air conditioner or window was a little difficult. You do have to climb one flight and then there is an elevator. The halls are narrow and the bathrooms were ok but the shower that was working needed cleaning. Not far from there is a Home Lisbon Hostel that was cleaner and cheaper for a shared space. I would explore hostels instead of Airbnb next time. It is fine if you are price sensitive.
