Designed to seamlessly connect main living spaces, the clean and natural flow of this fabulous home is conducive to everyday living whether indoors or out. The original hardwood floors add warmth and character, while abundant windows bathe the home in natural light. The thoughtfully updated kitchen with granite counters, custom cabinetry, and stainless appliances, serves to accentuate the welcoming layout. Perfect for summer grilling and entertaining, the generous patio and large backyard are easily accessible and fully fenced.
