Guilherme and Ananda were excellent hosts- their communication was really valuable both before and during the trip. We stayed with them for carnaval and G had recommendations on all the blocos and parties to go to- he even let us borrow costumes from his fancy dress box!
The flat is a gorgeous penthouse apartment in Copacabana- we felt safe here and it was so close to the beach.
We had our own bedroom and bathroom and felt comfortable using the kitchen and common areas - would recommend as a lovely stay in rio :)
