This apartment was perfect. Ideally located in Bairro Alto, it is near most bars and great restaurants, and its central location makes it an ideal home base for exploring the rest of Lisbon.
The street on which this apartment is located is quiet most of the time, and when it is a bit noisy with street traffic then the windows easily keep the noise outside the apartment. The apartment was stylishly designed, clean, and bright. You almost did not want to leave by the end of the trip. The stairs leading up to the apartment are a bit narrow, but that should be expected in older buildings, and it really is not an issue.
Overall, Nuno's apartment is amazing, and one of the better Airbnb's we have stayed at. When we return to Lisbon in the future, we would be so happy to stay at Nuno's listing, again. Definitely book if you are visiting!
