Had a great stay at Joana's flat. She was able to accommodate an early check in time and communication throughout my stay was great.
Location is convenient to a lot of great spots in the neighborhood and is also a good jumping off spot to explore the rest of the city. It is just a short walk to the closest metro / tram stops.
Bairro Alto is a happening neighborhood and, as others have mentioned, it can be noisy until early AM on the weekends. There are some heavy wooden shutters that help a lot. I am generally a light sleeper and still didn't have a problem.
Would absolutely stay again. Thanks!
