I've been staying in this beautiful studio in Copacabana beach from time to time for the past few years, and this year I've spent several months there–I've pretty much lived in Rio. I keep going back because of its location (safe; near the beach and transportations like subway, city bikes and busses); 24h doorman service; cozy apt with all appliances one needs and lots of art in the walls. Rafael is an amazing (and experienced) host who will be there for you whenever needed–including providing tips on the city's best local spots, from juice bars to hiking mountains.
