Filipa & Sergio's apartment has one of the greatest views in Lisbon. The building is incredibly old but the apartment is fantastic. You can really feel the old world charm but still have modern conventions. They only have space heating and if you turn both on at the same time the power will go out. Luckily the heaters work great and the fuze box is right by the apartment. No one was there to let us in when we arrived but they were communicative and remedied the situation relatively quickly. I would stay there again.
