This is an excellent, beautiful, superb spot which is immaculately decorated and renovated to be extremely chic and appealing.
Yes, there are slight imperfections here and there, but overall this is a top top spot in Rio.
YES, be aware you are staying a few hundred meters from the start of the favela. Uber won't go this far up the road. It is easy enough to deal with. Use the 99 taxi app. Use iFood for delivery. The favela is safe and there's no danger.
The only request I'd make is that some of the drains in the master bathroom are dealt with to block the smells from the pipes. If this is done this place would be completely perfect in my book.
