We really enjoyed staying at Fabiola and António's place. Their friend Luis checked us in and gave us good directions and tips for enjoying the area. The apartment could not be better located - it is right in the middle of the Alfama neighborhood where there are fabulous restaurants, cafes, and fado night clubs as well as beautiful lookout points and historic sites - right on the historic #28 hop-on-hop-off tram line as well.
The apartment is very well-equipped, the bathroom is all new and well-designed, and the bed was very comfortable. We were very comfortable there. Since the apartment windows both face out directly onto the street, with trams, cars, and many tourists passing by, it is necessary to keep the windows closed at night to keep out the noise and light - this is not a problem. We were actually happy that the apartment was on the ground floor so we would not have to lug suitcases up stairs.
We recommend this place to anyone who is visiting Lisbon for the first time and wants to be in the middle of the action - we feel this was a good choice for us.
