Ask HN: Where can I find hacker houses / co-living spaces in SF?

I've been in SF for a year now living alone, and I realized I have met very few people in my time here. I'm getting really intrigued by the idea of living in a community living space for a more social experience. I know I had heard of them being quite plentiful in SF, but I'm having a hard time finding them when googling now.

Ideally something relatively clean.
