    "Central to everything and great hiking nearby but also noisy, rude college kids. Lots of illegally off leash dogs. "
  • Jessica O.
    "Definitely a college neighborhood. Fun place to live, near campus as well as parties,but it is loud. "
  • Alec W.
    "College community. Sometimes you forget real people live right on the outer edges of it. Amazing place to live, tons of nightlife, and great food. Not where you want to live if you’re looking for quiet "
  • johnarmstrong
