My brother and I stayed at Bruno's apartment in Copacabana and highly recommend it. Bruno is very friendly and helpful, communication with him was very smooth and he met us promptly to deliver the keys (although I had not set up a specific time with him in advance!). His apartment is lovely, nicely furnished, clean and well kept. It is also within walking distance to lots of restaurants and the beach, as well as the metro station in Copacabana, which makes it a great location to explore Rio on foot. Highly recommended!
