I'm from São Bernardo, and I don't like it that much. Luckily it's not so hot as in Rio de Janeiro and fresher comparing to the stuffed wheather of São Paulo. But still, horrible traffics jam, crowded streets, buses...everything. Annoying!
All in all , not everything is rubbish ther, it's not that bad and you can always find amusing programmes to go and cultural events.
It's near to São Paulo, which is, by the way, much more interesting than São Bernardo. However, São Paulo is ever more chaotic and busier.
I think I would like to go to Floripa rsrs
