The appartment is small but cosy and perfect for two people. We stayed there for a week and had a great stay in Lisabon as the appartments location is very central in the Alfama, clos to the miradores and many nice restaurants as well as to the santa apolonia station from which you can take the metro/bus/train to other parts of the city. Yes the walls are thin but that's how it is with old builidings and we got used to it, no problem. The appartment was nice and clean when we arrived and Ana gave us a quick intro to the appartment. I can for sure recommend this place, we would definitely come back.
