Ask HN: Most interesting coworking spaces in Bay Area?

I'm going to be doing some serious, 60-hour-week work on a personal project over the next month and a half, and I was wondering if I should join a coworking space. As a solo developer, I usually work out of cafes and find it quite enjoyable: have a drink, do some people-watching, bask in the quirky atmosphere. The noise never bothers me, and, of course, it's very cheap. With this project, I have quite a bit more cash to play with, so I thought it might be nice to work out of an actual office for once. Looking around, though, it seems that many of these places are rather boring and "corporate", with an emphasis on productivity over everything else. I don't want to lose all the things that made cafe work great. I want to get a bunch of stuff in addition to that. Things I'm looking for: * Consistent power, Wi-Fi, etc. (obviously) * A well-designed interior; a cool building * Natural light! * Friendly community spirit; social spaces, Slack channels? * Comfortable chairs * Hardware perks, such as 3D printers or gaming consoles * Maybe lectures, events, etc. Don't care about private offices: open plan is a-OK. Not looking to pay more than ~$500/month. Anything you'd recommend in the Bay Area? Or maybe I should just stick to cafes? Thanks!
