Abundant natural light, outstanding outlooks and a rare flat backyard come together at 185 Circle Ave, a beautifully updated 4-bedroom, 3-bathroom home in one of Mill Valley's most desirable settings. Set above the golf course with sweeping views toward the hills of Mill Valley, the home enjoys a peaceful, elevated position while remaining remarkably close to town, schools, trails, and everything Mill Valley has to offer. The level backyard a true rarity with a lawn/turf, patio space, mature landscaping, and room to sit, play, garden, and entertain. Walls of windows bring the outdoors in, with the living room framed by expansive glass overlooking the backyard and out over the golf course beyond. A gas fireplace with newly refinished tile surround, and warm hardwood floors create an inviting gathering space. The adjoining dining room continues the view. The thoughtfully updated kitchen features stainless steel appliances, new counters and backsplash, designer-selected interior colors, and exceptional natural light, including a charming window nook. The bedroom layout offers both connection and privacy. The spacious primary suite has a wonderful scale, sliding doors opening directly to the patio and yard, a large walk-in closet, and a light-filled bathroom with double vanity, shower, separate tub, and plentiful storage. Two additional bedrooms are located nearby and share a full bathroom with oversized shower and double vanity - while the fourth bedroom suite off the kitchen offers excellent flexibility for guests, an office, or family members, with its own bathroom and direct access to a private brick patio. Transom windows, large bedroom windows, and thoughtful sightlines throughout the home maximize the natural light and connection to the surrounding landscape. With hardwood floors throughout, beautifully refreshed finishes, generous storage, interior access to the one car garage, multiple outdoor spaces, and an exceptionally livable floor plan, 185 Circle Ave offers something increasingly difficult to find in Mill Valley: big views and a backyard you can actually use. Add in the area's famously favorable climate and convenient location, and this is a home that delivers an unusually compelling combination of setting, scale, indoor-outdoor living, and everyday comfort.
