We had a nice stay at Leo's place. It was a nice private space on the top floor of an apartment.
Leo's brother Raphael also kindly picked us from the airport for a small price which was really kind.
The only drawback I would say is the location which can't be helped of course. But if you're wanting to visit the main sights in Rio then an Uber is around $30-$40 Reals to the main spots e.g. Copacabana, Sugarloaf mountain etc.
Other than that we really enjoyed our stay and the air conditioning in the room helped with the hot nights.
Thanks!
