We stayed for just under a week at Catherine and Alan's place in Copacabana. Catherine was very easy to communicate with, and was incredibly helpful with tourist and non-tourist things to do in Rio. I couldn't believe that they provided us with tea, coffee, fruit and cereal for our stay -- I haven't had better hospitality in some 5 star hotels. Other reviewers have mentioned that the place is "cosy" (which I confirm), but for us it was fine. On top of everything, Catherine and Alan have tastefully decorated the apartment and have quality appointments. I would definitely love to stay here again, and would highly recommend it to others.
