I found Lawrenceville to have a small-town vibe - being conveniently located down the street from downtown Princeton and the prep school. The properties in this area of 206 are mostly older homes, but many of them have nice size lots.

Again, this is my opinion having traveled through Lawrenceville for a few years.
Visiting websites like city-data, nationalrelocation or wikipedia may offer additional stats for the area.
