The apartment was perfect, just as described and shown in the photos. It was extremely central, right in the center of the Alfama district and a ten minute walk from the main drag, or less than 50 meters from the tram stop if you don't fancy the steep inclines. We were met by Pedro who gave us a very detailed description of the area and plenty of suggestions of what to do and where to eat/drink, which came in very handy, as well as being accommodating to our late arrival. The upstairs neighbor is a bit odd, and she likes to sing, but it didn't bother us.
Overall an extremely pleasant experience, thank you very much
