Sergio's place is on the fourth floor of a cool old building in a beautiful square in the Alfama. We could hear lovely fado music through our window every night from the restaurants below and felt like we were experiencing the heart of the neighborhood's historic past. The place was clean and had some great touches like a hammock that was nice to relax in after long days walking up and down Lisbon's hills. He shared an awesome google map with recommendations of places to eat and things to do in the neighborhood. The ceilings are a bit low, especially upstairs in the lofted bedroom and in the narrow stairwell, so this is probably not the place for you if you are on the tall side or have difficulty with steep stairs. The apartment is close to the river, close to public transit and a great hub for a week in Lisbon. Another nice touch was a mobile wifi spot that we could take with us when we were out and about during the day.
