Great little guest house in a family's backyard with a separate entrance. You can hear a train pass by in the distance, but even with the windows open, I never woke up to it (and I'm a very light sleeper). It was the perfect location for us, as we had family in Palo Alto - 10 min walk across a pathway over the creek that separates menlo park from Palo Alto. Also, relatively close to the mall and other restaurants. Also loved the quiet neighborhood atmosphere.
