For more than 40 years, 3306 Cathedral Avenue has been owned by one family and its rooms filled with decades of memories. Ideally located at the intersection of the Cleveland Park, Woodley Park, and Massachusetts Avenue Heights neighborhoods, this 1924 Colonial Revival row house sits above the street beneath a canopy of mature trees. The classic Washington residence with genuine architectural character is a wonderful opportunity to own such a beautiful residence located in a sought-after neighborhood. The main level opens from a traditional entry foyer into a gracious, light-filled living room anchored by a rebuilt wood-burning fireplace, with French doors leading directly to the rear garden, ideal for both everyday life and entertaining. Across the foyer, the formal dining room enjoys wonderful natural light and connects to the kitchen through both a doorway and a charming pass-through. The kitchen offers direct access to the rear terrace and garden, where mature greenery, flagstone, a small patio, and a hot tub set the stage for an intimate outdoor retreat. Upstairs, the comfortably sized primary bedroom offers an en-suite bath and a relaxing space to unwind, while two additional bedrooms share a hall bath; a linen closet completes this floor. A staircase leads to the top floor, where a freshly painted, carpeted space with a cedar closet unfolds beneath a pitched ceiling. Currently open and flexible, it offers potential as a bedroom, home office, studio, or playroom. The unfinished lower level offers substantial storage, laundry, and additional possibilities, along with interior access to the one-car garage. Two additional surface parking spaces provide convenient off-street parking. This property offers a rare opportunity in one of Washington's most desired neighborhoods. The home is walkable to Metro, Rock Creek Park, and the vibrant retail and dining corridors of Connecticut Avenue and Cathedral Commons, independent and public schools, and the National Cathedral.
