I very much enjoyed staying at Renata's place. The location right at the corner of the main beach front avenue in Copacabana is indeed ideal. The host is very responsive and I felt that the value for money was good because of the location. The main drawback for me, which might not be one for someone else, is that there is a hotplate but no microwave in the apartment. That said, I would still rank this as one of the better airbnbs I have stayed in in Brazil.
