The stay at Luis' was nice and the apartment basic but comfortable and cheap. Luis was always helpful if something was needed. The location is great, very central in Lisbon and close to numerous restaurants, bars and accessible from everywhere in the city. While the place is fantastic for anyone coming to Lisbon for leisure and partying (right in the heart of the very animated Bairro Alto), I wouldn't advise this place for someone coming for work, as it gets very noisy at nights, with numbers of bars just underneath and quite a bit of noise until late at night (+ early in the morning with the school just opposite). The place could also be a bit cleaner with unpleasant smell in the bathroom.
