stayed at Patrícia and Bruno's for three days and loved it there!
the location is central, easily reached places like Ribeira, the Luiz bridge, etc. also, some cool places to eat at around 10ish minute walking distance.
the place itself is quite lovely, sort of has a feel to it, good vibes.
the hosts were terrific, helpful and kind, went an extra mile with nice little things and tips.
would definitely recommend (and would like to come back someday too!).
