Our stay at Ana Chrystina's apartment in Copacabana was absolutely excellent. It is ideally located, close to the beach (yes, the ONE, Copacabana!) and at the heart of a very lively neighborhood. It's an excellent choice, with a tasteful decoration and plenty of great books to read (if you have time to do so!). And Ana Chrystina is a lovely person. We'll definitely try to rent her apartment again when we come back to Rio de Janeiro. Excellent for families (we have 2 kids. They were 9 and 12 at that time and they loved it) and great value for money.
