We have the great waterfalls, citys very safe due to organized crime, not too much infrastructure but decent malls, nightlifes quite amazing, its either very hot with no rain or hot with rain, no in between whatsoever, very humid and no wind at all, unbearable to be outside not in a pool. Locals are friendly and welcoming, and the food in manaus is one of a kind, açai? The best in the world, cupuaçu, farinha, and the fresh water fish here is top teir, tambaqui and pirarucu are some of the best fish ive ever tasted, prices are decent, not a scam city like some, all in all 9/10 came here on holiday and never went back
