Not what I expcted
It was just sad to see how many homeless people populate Sn Fco. Everyone tells you it is a beautiful city but the homeless situation is a huge problem. Lots of them, too many of them, everywhere.
I have traveled in. Mexico, Brasil, Chile and Argentina and I have never seen so many of them in a city area. I just did not feel safe walking around, and they were agressive enough to demand that you bought them food or coffee wherever you went.
Insider Tip:Dont stay near downtown or Chinatown, it is simply unsafe. Pay extra to stay near the coast or you will not be able to enjoy the city by foot, which is the ideal way to see it.
