    "This tucked away area on the waterfront in Mill Valley is something of a secret! Even long time residents aren't familiar with this wonderful enclave of luxury homes.. A quiet side street from Strawberry Drive leads to the Bay front and these gorgeous homes on the water with their own park and Bayfront walking path. Great weather, great commute. Close to Harbor Point club with tennis and swimming, a great cafe and spa. Walk to shopping at Strawberry Village or the Cove or a quick commute to almost everything including San Francisco. What's not to love?"
