Whoa really? I have absolutely no idea how BsAs can rank so high. It used to be a nice city 10 years ago - nowadays it's decadent. Thousands of people living on the streets inflation makes things extremely expensive (for Latin America), and locals are just tired and sad. I've been there 4 times in the last decade and could witness the decay of their once beautiful city. Definitely not on my top 100 list.
