Study abroad in Brazil

I am considering studying abroad next year in Brazil. The main location for most programs seem to be in Sao Paulo. I was just wondering if anyone who knows the city can offer some suggestions, tips or insights on things like crime, lifestyle, nightlife and possibly where to train some BJJ/wrestling/MMA for a college student. I can speak a little Spanish, but as of now can't speak any Portuguese, however if I decide to go I will definately try to pick up as much as I can before leaving. So if anyone can tell me anything about the city, all I know is its huge, I would greatly appreciate it. Thanks.
