We where 3 persons. The flat is verry central in a sweet and calm neighberhood where you can find (in mine oppinion) the best breakfeast spots in lissabon, a lot of small handmadeshops and houses with many great azulejos. The metro isn't near but the bus station is just around the corner. The flat is verry modern, the bed comfortable, the kitchen is big and if you travel with kids it has also a extra bed for a children! Stay in charles and annas flat to discover lissabon from it bests.
