Well, I wouldn’t really recommend you to take public buses, they’re not very safe, so don’t do it. Metro is much better, it’s cleaner, it’s faster and you can get pretty much anywhere in the city, so you shouldn’t take buses. And also you should avoid downtown during night, night time, it’s quite dangerous I think as any other big city. It is like any other city in the world, it’s kind of dangerous when you go downtown at night time. So I think those would be my tips for you.
