I really enjoyed staying in Thiago's apartment. The apartment is just across Avenida Atlantica from Copacabana Beach near the new museum that is being constructed. The apartment is on the 9th floor of a good building with an amazing view of the beach. The apartment is surprisingly large and even has a clothes washer. There is excellent wifi, A/C and soundproof windows that let you shut out the street noise when you are ready for bed. It's nothing fancy, but the apartment has everything you need to have an excellent stay in Rio.
