Charming, updated, and full of possibilities, this 1944 Cape Cod blends timeless character with modern functionality in a peaceful, quiet-street setting. From the moment you step inside, you’ll appreciate the home’s classic appeal, highlighted by graceful arched doorways and rich hardwood floors that flow throughout much of the main living spaces. The kitchen offers a stylish modern farmhouse feel, complete with coffee & wine bar. The rear addition creates a bright and versatile living space. Upstairs, the second floor provides a cozy yet spacious retreat with flexible layout options. Whether you envision a primary bedroom sanctuary, a welcoming guest space, or a tucked-away office nook, this level invites you to make it your own. The lower level, currently used as a workout area and playroom with a full bath. Ideal for creating additional living space. Step outside to enjoy a generously sized, fully fenced backyard with mature trees and perennials, the back deck is serene day & night.
