We stayed at Rosário's place for 4 nights and we felt warmly welcomed. Rosário is the best host and helps with any problem. We had our own privat area with a bathroom and shared the kitchen with her. The area was secure and had a door man who let us into the building everyday and night. It' close to the bus station which brings you either up north to Centro or south to Copacabana and Ipanema.
We really recommend staying with Rosário!
Thanks a lot for everything Rosário!
