We (2 people) stayed in this charming little studio in Copacabana for one week. The kitchen is reather small but sufficient for small dishes.
The location was good. Copacabana, Ipanema and Leblon can be easily explored with bikes and the city center can be reached with the near by metro. Overall we really enjoyed our stay.
Carolina was really helpful and gave us a lot of tips for the city and also arranged the pick up back to the airport.
