We had a great few days staying at Rafael's lovely apartment - the location is excellent, a stones throw from the beach, and the space was clean and comfortable (especially the hammock!). We felt very safe in the area, even walking around at night, so no concerns there at all.
Rafael himself was really welcoming and friendly, and went out of his way to make our stay as straightforward and enjoyable as possible. His local tips and advice were also very helpful!
Overall would definitely recommend, and wouldn't hesitate to stay again if we are back in Rio!
