We thoroughly enjoyed our stay at Pedro's. The apartment is in the heart of Bairro Alto and we couldn't have asked for a better location. All of Lisbon's top tourist destinations are in walking distance, as are the main train stations for day trips out of the city. Although the street below the apartment does get noisy in the evenings (as others have noted), the windows and doors of the apartment were quite soundproof and we were not bothered by the noise at all. Pedro was a great host; he provided fans to keep the apartment cool and also gave us two sets of keys. It was the perfect space for our first trip to Lisbon!
