We thoroughly enjoyed our stay at Rogerio's apartment. It has a very accessible location near to the Copacabana beach (3 mins walk), subway station (10-15 mins walk), supermarkets (5-10 mins walk), restaurants and pubs (5 mins walk). As it is located on the same street as restaurants and pubs (further down the same street, so the apartment isn't noisy) and just a block from the main street, it was safe for us to walk home at night.
Rogerio was a wonderful and friendly host. In spite of his busy schedule, he brought us around for a short tour and shared stories with us so that we could better understand and appreciate Rio. We definitely recommend staying at Rogerio's when you visit Rio de Janeiro.
