Marcelo is a fantastic host. In addition to being an absolutely lovely and caring human being, he is very knowledgeable about Rio (among other things) and can give you precious advice on what to see and where to go. The rooms are beautiful and furnished with care and personality. The common parts of the house (including the pool) are great too. It is perfectly located if you want to see more than Copacabana and get the pulse of the "real" Rio. I highly recommend you stay at Marcelo's!
