856 Marco Pl Nantucket cottage charm meets sophisticated California coastal living in this enchanting walk-street compound. Behind a white picket fence and lush privacy hedges, a thoughtfully updated three-bedroom main residence and breathtaking two-story guesthouse unfold around a serene, storybook garden setting. The sun-drenched main home blends relaxed coastal character with a refined design-forward sensibility. Walls of windows capture sunshine and ocean breezes, while seamless indoor-outdoor flow opens you to a beautiful front garden with inviting living and dining areas, fire pit and peaceful fountain. A romantic open kitchen overlooks the dining, living and garden spaces, while connecting seamlessly to the rear deck, barbecue and wellness area. A farmhouse sink, elegant quartz countertops and top-of-the-line appliances make it ideal for both casual living and entertaining. A "Pure Effect Whole House Water" system throughout the property removes impurities, and combined with a water restructuring system that mimics the natural flow of rivers and streams, elevates the experience of everyday life: drinking, cooking, bathing and home cleansing. The private backyard enhances the wellness ambience with an infrared sauna, outdoor shower, grilling area, Ipe deck, and a spacious indoor gym. The newly built Guesthouse/ADU is a showstopper, with a window-filled upstairs living space and large roof deck. A true rooftop oasis, it offers a Jacuzzi spa, a cold plunge, an outdoor fireplace and lounging area overlooking expansive sky and mountain views. With storybook curb appeal, lovely gardens, and natural materials throughout, 856 Marco Place delivers a rare combination of character, privacy and modern luxury, all within easy walking distance of Abbot Kinney, Erewhon and the best of Venice.
