Very beautiful flat, in the center of Lisbon and for sure in a nice district which moves on the night. You can also try the "best mojitos of Lisbon" nearby the flat and eat very well, so the street is a bit noisy but don't worry it is not too disturbing. Antonio is so nice, so accommodating and flexible if you have any question, I really advise you to choose this flat if you go to Lisbon for some days. :)
