Alexandra & Pedro's place is ideally located for wandering Alfama, which is exactly what we wanted to do. As of March 2019 there's a building under construction nearby, however the windows are great at keep most of the street noise out of the apartment. There's so many improvements being made to Lisbon in general, especially Alfama, it would be difficult to find a place that isn't near construction.
The apartment is very nice and has a well appointed kitchen, if you're interested in cooking. Enjoy the sounds of the neighborhood, especially the Fado place next door with the windows open.
