With three bedrooms and two-and-a-half baths, the layout lives expansively, enhanced by abundant storage and thoughtful separation of living spaces.Floor-to-ceiling glass sliders in the main living areas and primary suite face east, capturing peaceful sunrise light over Sarasota Bay in a setting best described as park-like waterfront—where mature coastal trees frame the water, creating a serene, private “treehouse” ambiance. Boats glide through the mangrove preserve and lagoon toward open bay waters, accompanied by birdsong and rustling leaves. Two balconies extend the living space outdoors, including a nearly 400 sq ft screened lanai ideal for relaxed coastal living. The primary suite features bay views from bed, terrace access, dual walk-in closets, and a spa-like bath with a freestanding soaking tub, dual vanities, and a glass-enclosed shower.The second and third bedrooms share access to a west-facing balcony, offering sunset light and cross-breezes.The kitchen is both functional and social, featuring quartz countertops, a Sub-Zero refrigerator, generous prep space, a built-in desk nook, mini-fridge and wet bar—well suited for entertaining or casual mornings.
