Having stayed in many parts of Rio de Janeiro, this was a unique experience all of its own. One of the differentiating factors was the amazing view of the Atlantic Ocean. The environment in the Favela isn't how people would imagine it. It's peaceful and it's like a community of it's own. There are places to eat, bars and even a store to purchase goods if you don't want to walk down or take the Bonde. You will definitely stay in shape climbing the stairs to the accommodation.
During the summer, the air conditioning will cool things down or open the window for a nice breeze. During the "winter", it can get a bit cold, but it's tolerable. There weren't any issues coming and going at all hours of the night and safety wasn't an issue. The people are very warm and welcoming.
