Claudio is a great host and his place is the perfect for a couple or a single person to stay in Rio.
I knew that Leblon was a good neighborhood, but only after getting there you realize how amazing the location of his apartment really is.
You have everything you can possibly need Within a two-block radius and getting around it's very easy and cheap even only using Uber, which by the way it's dirt cheap compared to US.
I highly recommend his place.
