I've actually been working out of this space for the past few weeks. Don't have kids but I see everyday how amazing it is for all the people who work there who do. The daycare is sectioned off so there isn't a whole lot of noise or distractions from the kids.
If you're based out of SF, freelance / work remotely, and have kids, I think this is a fantastic setup.
