This distinguished Craftsman pairs period detail with thoughtful updates across a beautifully proportioned, versatile floor plan. A gracious entry sets the tone, opening onto connected living spaces built for both daily life and entertaining. The formal dining room, anchored by a picture window and original built-ins, flows into a sunlit breakfast nook and an updated kitchen with an expansive island and premium appliances. The main level also holds a living room with fireplace, an adjoining family room, a home office, and a powder room; French doors lead to an inviting patio suited to outdoor dining, lounging, and entertaining. Upstairs, a striking landing sets the scale, opening onto four bedrooms and two updated baths, with a front balcony hot tub positioned for stargazing or morning coffee. The top floor adds a fifth bedroom suite with an adjoining flex room, ideal for guests or a private office. The lower level offers exceptional flexible living space: a living area with fireplace, full bath, and its own entrance, well suited as guest quarters, office or teen space. A gym and ample storage complete the level. 340 San Carlos Ave. is set on beautifully landscaped grounds with easy indoor-outdoor living, just moments from Piedmont schools, parks, and the new pool.
