We were met by Mariana, a friend of the host, who graciously showed us around the apartment, showed us a bunch of points of interest on a map of Lisbon that she left with us, and then walked us down the street to a delicious African restaurant. The neighborhood is nice - in the older part of town - within walking distance of pretty much everything in the city center, especially the castle. Only criticism would be that the beds were not super comfortable, but overall we were very happy!
