we spent 2 weeks in Luis's Copacabana apartment for New Years. The location could not have been better, very central in Copacabana, 5 min walk from the beach and the metro station. Lots of cheap and good places to eat and supermarkets all nearby. The apartment is basic, but clean with all the required amenities in working order, it has everything you need for a comfortable stay. Its also a secured block with 24hour doorman. Luis is also very friendly and helpful, offering tips and suggestions for a safe and comfortable stay. Overall would recommend this place for a great stay in Rio.
