Built in 1928 on a quiet corner lot in one of Cos Cob's most desirable neighborhoods, this move-in ready Colonial has the character of its era with the updates today's buyers are looking for. The kitchen flows into the family room, where extra-height ceilings and a skylight pour in natural light. A fireplace anchors the living room, and a full bath on the main level adds everyday convenience. Upstairs, the sun-filled primary suite includes a steam shower, with two additional bedrooms and a full hall bath. The finished lower level complete with a half bath, which works as a home office, playroom or guest suite. Outside, a private deck and an oversized lot offer real potential. Proximity to town, to commuting options, to the water: it's all there.
