A really great location in the beautiful back streets of Alfama. Many outdoor eateries, live (unamplified) fado music beneath your balcony, a lively flow of locals and tourists, and just 2 blocks from the waterfront & public transit stops that will take you directly to many other Lisbon highlights.
The kitchen is well stocked and has a new washing machine under the counter.
The street activity winds down around 23:00, so sleep is undisturbed.
Really the only con is that the musicians partly block the stairs to the apartment so it can sometimes be a little awkward leaving or returning.
