It's relative -- among Seattle hoods, I would (anecdotally and out of my ass, of course) say there is more violent crime there than in others. I'm also a fairly big guy and I've felt uncomfortable plenty of times there at night when the streets are semi-abandoned.

In the past year I've seen ambulances taking away normal citizens who've been beat down (twice) and I've had a stabbing perp run by me as he was chased by the cops. And this is with me almost never going to Belltown. I've never seen anything remotely like that while I lived in First or Capitol Hill (although I've definitely seen plenty of car break-ins).
