Ask HN: Visiting SF on a Budget?

I want to do a trip to SF to sightsee and network.

But I want to keep costs down.

Hotel / AirBnB are the easiest options, but what about co-living spaces and hacker houses?

Ideally want to network with people working on llms / ml ops, so the community of a hacker house is appealing.

But never stayed in one before, so not sure what to expect!

Any help would be appreciated.
