Otávio's apartment is very centrally located in the centre of Copacabana, you'll find all kind of restaurants, bars, supermarkets nearby, the beach is located only 2 1/2 blocks away, less than 5 minutes.
The apartement itself is rather basic, but there are two separate rooms, a small kitchen and a working bathroom, if you consider the fair price, the relationship is quite good.
The only negative thing I can mention is the neighbour below the apartment, turning on his TV with maximum volume at 12 o' clock and turning it off between 11 pm or midnight, moreover several dogs barking, so it's not really quite, though it's on the top-floor. The street was no problem for me, though.
Altogether it was okay, I can recommand it to other people looking for an economic and central apartment.
