The flat is a few minutes' walk from public transit (be prepared for cobblestone and a slight hill with luggage) and is a leisurely walk to many of the popular destinations in the area. It is well lit and quiet at night. Its location feels like a neighborhood, rather than something in the middle of the tourist fray.
The apartment is similar, but not exactly like the photos. It now looks a bit more "lived-in", has different artwork, one window has a shade instead of drapes, the walls have a different paint pattern and the sofa has had some fading from sun.
Lisbon is known to have an issue with dampness in its older buildings, so be sure to inquire about moisture/mold. There is a humidifier in the flat.
My only concern was related to cleanliness, which Joana quickly took steps to address. She was a responsive host and I appreciated that she checked in to see how I was enjoying my stay. The flat is equipped with a local map that is marked with key locations and there is a selection of tourism brochures available. This flat could work for the casual traveler or teleworker.
