My very limited experience with Mexico City is that I'd treat it like many U.S. cities: it's fine, if you know which areas to avoid after dark, and which areas to avoid entirely. It is not like a safe European city center where you can go almost anywhere alone on foot at any time of day. But most U.S. cities don't fit that description either. And it's not at the other extreme that some people imagine, some kind of Somalia-esque set of private compounds separated by lawless warzones.
