Well, the police recently ran a sting on my street and discovered that within 10 minutes of leaving a bicycle unlocked/unattended, someone will be along to steal it. That's not even an average, it happened in every case. It's really just a small % of losers/thieves who have traveled over from a few blocks away, though, and most people on my street are actually okay. This area is very block-to-block in terms of nice/dangerous areas.
Other than that, the neighborhood is okay. The buildings are older and not in the best shape, but that's true in many parts of the city. I'll probably move out to the 'burbs in a couple of years, though. Getting asked for money/change several times a day just gets old. Some are annoyingly aggressive about it, too, like they think I owe them a toll.
