Charming Historic Federal on Coveted Cobblestoned O Street Nestled on one of Georgetown’s most picturesque blocks, this semi-detached Federal-style residence offers timeless elegance and rare privacy thanks to its deep setback and elevated position. Built in 1840, the home retains rich original details—wide-plank hardwood floors, a period mantel framing the wood-burning fireplace, and generous windows that bathe the home in natural light. The main level is designed for both refined living and effortless entertaining, featuring a sophisticated living room with original fireplace and a formal dining room ideal for hosting intimate Georgetown dinner parties. An updated kitchen with stainless steel appliances opens to a beautifully landscaped, multi-tiered brick patio—an inviting space for al fresco gatherings. A powder room and laundry room on this level add everyday convenience to the home’s historic charm. Upstairs, two well-proportioned bedrooms share a full bath, while the lower level offers excellent storage space. Located just steps from Wisconsin Avenue, vibrant M Street, charming parks, and Georgetown’s finest shops and restaurants, this is a rare opportunity to own a piece of D.C. history in one of its most desirable neighborhoods.
