Most things downtown are expensivey, fff. Maybe the Financial District or SoHo? They kind of overlap and you could reasonably find an office building or lab-type-thing in either of those areas.

However both Spidey's Manhattan turf and moving to Bedstuy puts him solidly in Jason's places of business. I'd be open to doing something with that if you want, or we could handwave some kind of deal? Idk man, up to you.
