    "I’ve lived in Napa for 33 years. It’s a great place to live and raise a family. It’s not the small town it used to be but it still has some of the small town character and feel. "

    "This is an older neighborhood with mid century houses. However the access to all of Napa and the wineries is excellent. The access to shopping is excellent. Houses are being redeveloped and the values continue to increase."
