@Jans: Hello! I'm working!
My company decided they needed someone here so now I'm here...
@US: That's an interesting question. I would say the nature is definitely as exotic if not more than I personally imagined. The city itself, architecturally, is a lot less exotic, depending on how you see exotic. Full of mostly socialist looking residential 60s 70s buildings, the old center is mostly overtaken by these monstrocities, but there are some vestiges of the old imperial Rio.
Copacabana for example, is something you see once and never return to. Huge and overpopulated, and frankly, a bit dirty.
For a holiday, I would say it would definitely be worth seeing, for living, not so much. Too expensive, too crowded, too dangerous.
