I spent a month in George's penthouse — a spacious, split tri-level industrial loft perched at the top of Babilônia hill.
You'll have to "hike it" to reach it but babyyyy, let me tell you(!!) — those 360 panoramic views are worth the trek. (And if you happen to be "home" at dusk, be sure to step out onto the deck to take in the chaotic sonatas of the Babilônia community either returning home or working their way out. The vibrant chatter erupts and crescendos to an explosion of melodic arias. What do they say: Music to your ears? An accidental impromptu you must hear!)
Full disclosure: I did experience the hiccups and "challenges" — no spoilers(!!) — that come with long-term travel. Look: You either want the full and authentic experience of "living in a favela" or you don't. If you describe yourself as a go-with-the-flow, rough-and-tumble, nimble-like traveler — I would encourage you to book now; you won't be disappointed. Think — more savant, less nitpicker.
Safety: I used the same techniques I use in the US (e.g., city, surburban, rural) and nothing more. I returned after midnight on several occasions and felt completely safe.
George: Part anthropologist, sociologist, historian, and philosopher with a wealth of information on Brazilian culture, politics, and society. He'll also give you great need-to-know tidbits to make your stay more fluid. Also (imho), he does expect an independent traveler (as he should); so, don't expect him to hold your hand.
TLDR — A decadent pitch high in the sky that satiates the heightened curiosity of the adventurous, laid-back globetrotter.
