    "Good area a bit worried of the speeding on marine view ave very loud cars driving by and speeding I do see kids playing outside wish they would have a police officer monitor the speeding. "

    "Good quiet neighborhood with convenient access to Caltrain and other amenities like parks and trails."
  • Yuqing P.
    "Commute to SF everyday. Caltrain is 15 minutes walk from my place. The local train takes about 50mins to get to SF. If you can drive to Hillsdale, there is bullet train."

    "That you need to watch kids closely as cats do speed through the streets occasionally (a neighbor’s dog was recently run over and they didn’t stop)."
  • Lsurley
    "It’s a small neighborhood. Many people don’t know it. We spent a lot of time in San Carlos, which is very close."
