I really recommend to stay at Sarah's place.
The booking was very easy.
And the flat was very nice: a lot of space and charm, very well decorated and well maintained.
I especially liked the kitchen with its french touch.
It's good to feel at home.
In addition to that Sarah sent us some recommendations before arriving to prepare our stay, e.g how to come from the airport to the flat.
And she also shared some good tips not available in the tourist guides about what to visit, where to eat and have a drink.
I enjoyed a lot my stay in Rio at Sarah's place. I hope I can come back soon.
