We stayed at Denise's apartment during the World Cup, and our stay in Rio was absolutely great. The apartment was basic and comfortable, in a safe location, and within walking distance of the beach and restaurants/bars/markets as well as the lake, which made it very accessible. The metro is also very close by, and the neighborhood is residential but lively. Denise was extremely helpful and responsive to us throughout the process, and we certainly recommend this host and property.
