A friend has just set up a co-working space in Brooklin. Why? Simple, people want to have a creative space and other people to orbit around. These spaces are usually hard to find and expensive in Sao Paulo (the other one I know of is on Rua August). If you are setting up a company, or here for the long-term and need a space to work out of check it out!
