Marcelo's apartment was lovely, clean and in a fantastic location. Wifi was fast and hot water/water pressure was great. Near all the best restaurants, right between Leblon and Copacabana (and next to the beach!) and much less touristy than Copacabana while still being very secure.
As a head's up - there is a group of homeless men living directly outside of the entrance of the building, and while I understand that is the reality in Rio, I was a little worried at first as a solo female traveler. Marcelo was very receptive about my concerns and I ended up feeling very safe during my entire stay. I would recommend this place to anyone!
