Overall, a great stay in Bairro Alto! We were able to access the apartment immediately upon our 11 am arrival, and Raquel had left a fantastic package of great recommendations for maximizing our time in Lisbon - restaurants, sightseeing, etc. We stayed Thursday - Sunday and the streets of Bairro Alto are extremely lively; it was great to be in the heart of all the action and very convenient for our stay. As other guests have said, it is quite noisy until late, but not a problem if you're out enjoying the city!
