This is a really nice place in a good neighbourhood in Rio.
You can take the busses to nearly anywhere. We didn´t meet Marcella personally but it was easy to communicate with her. She always asked if she can do/arrange something for us.
Her housekeeper is nice and speaks English (not very common here).
The place is as described. You can sit in the garden and enjoy the breakfast. Fantastic.
We would come back any time.
