Sounds nice until they piss, shit, and do drugs everywhere and get your entire company evicted by the building owner.
I used to live nearby Twitter HQ and that description is unfortunately accurate to my experience, of the majority of the homeless who spent time at Van Ness and Market Street SF.
HOUSING is what is needed, for sure though. Just be serious about it, and not "diamond-mine trust-fund hyper vigilant ego-abusive maniac" about it.
