Welcome to 16 Nelson Avenue, a beautifully presented four-bedroom home in the heart of the Mill Valley flats. Set on a tree-lined street just a few houses from beloved Sycamore Park, this is one of those special locations where neighborhood life is right outside your door! Downtown Mill Valley, The Lumber Yard, local schools, restaurants and everyday conveniences are all close by, and San Francisco within easy reach. Bright, warm and inviting, rich hardwood floors complement the open living and dining spaces, anchored by a cozy wood-burning stove and filled with natural light. The spacious kitchen features high ceilings, generous proportions and an easy connection to the main living areas, creating a comfortable flow for both everyday life and entertaining. The thoughtful layout offers wonderful flexibility, including a generous primary suite that opens to its own deck and the backyard beyond. Impeccably maintained and move-in ready, the home has an easy, comfortable quality that feels welcoming from the moment you step inside. Outside, mature olive trees frame the landscaped front yard, creating a beautiful sense of arrival. The backyard is equally inviting, with charming brickwork and an abundance of fruit trees and plantings - including apple, fig, Meyer lemon, pomegranate and persimmon - creating a wonderful setting for outdoor dining, entertaining and play. A long driveway leads to an unusually large two-car garage, offering exceptional parking and storage along with possibilities for a home gym, studio or workspace. With its lovely outdoor spaces, exceptional convenience and coveted Sycamore Park location, 16 Nelson captures so much of what makes living in Mill Valley special.
