We enjoyed a wonderful stay at Roberta and Mauro's place in Cobacabana. The location is excellent...one block (2 min. walk) to the beach. It is also surrounded by many delicious restaurants. We went to a different place nearby every day and they were all very good. There are also city bikes to rent right outside the apartment building door. There is also a doorman to let you in, which makes it feel very safe. The apartment had so many amenities and the hosts were SO helpful whenever we had any questions. I would definitely stay here again and would recommend anyone coming to Rio to stay here!
