We stayed here with another couple and it was an excellent location. With the back door & windows open, we got a nice breeze, and appreciated the private patio outside. (though in the summertime, know that the window in the second bedroom has AC venting into it, and makes things hotter).
This was a great location in the Alfama, and we enjoyed being so close to the train station. It can be loud for that neighborhood, as there is a popular bar across the street, so be sure to pack earplugs.
Sandra was very helpful with providing recommendations and answering any questions-she really cares that her guests have a good time in Lisbon!
