According to this article, "The Barn Khayelitsha is an incubator for entrepreneurs with a focus on tech and innovation, as well as empowering women in business and youth in tech.".
It isn't a huge facility, but it does have one or two large rooms with rows of computers, as well as a section with desks and meeting tables where entrepreneurs can come sit with their laptops and work on their projects. They offer free wifi, and even have a small kitchen for making tea and coffee.
I was surprised, and delighted, to find The Barn in such an impoverished community. Good on you CiTi!
