I stayed at Mauricio's 4 night at the beginning of February. The apartment is in Leme, north side of Copacabana. It's in a very safe area and very convinient to any transports (bus, metro and bike sharing). There are also several restaurants in a very short walking distance and the supermarket, plus many other shops, just downstairs. The bedroom literally faces the beach/ocean. Mauricio is more than helpful and very kind. He will give you all the info you may need. Thanks!
