The new startup ecosystem in SF (including Ycombinator itself) has moved to the Dogpatch and Mission Bay area (https://maps.app.goo.gl/62FCMHEQWsMD2yHq7) of SF. You will not encounter needles here. I never even see any homeless here. It doesn't really "feel" like SF, but it is very walkable and bikeable. It is very clean.
I think a 1 bedroom apartment rent would be around $3500 now (and all of the buildings here are fairly new)
