We loved our time at João's place. It had a great location in Bairro Alto, close to a bunch of great bars and restaurants. Centrally located and close to the metro line, as well as multiple other neighbourhoods. Apartment was perfect for our needs for 2 people, and was an ideal home base for us for the month that we spent here in February. Streets could be a little loud at night with all the bar-goers, but it would quiet down and is easily ignored with the windows closed.
