Description

An inviting open front porch sets the tone for this charming, beautifully maintained vintage Colonial. Step into a welcoming foyer with built-in window seats, leading to a bright living room filled with windows and natural light. The updated kitchen features stainless steel appliances, granite countertops, counter seating, and an eat-in area. At the rear of the home, an expansive great room offers vaulted ceilings, exposed beams, a skylight, and Andersen windows and sliding doors. With ample room for lounging and an additional dining area, this gathering space is a standout feature. A full bathroom with a walk-in shower and a versatile room currently used as a home office, with potential for a first-floor bedroom, complete the main level. Upstairs are four generously sized bedrooms and a full bathroom with a tub and skylight. The private backyard features an L-shaped in-ground pool, green space, and room to relax and entertain. A detached former two-car garage offers additional space, adding to the property’s versatility. Central air conditioning and a roof approximately five years old add to the home’s appeal. Set in close proximity to the elementary and middle schools, this character-filled home is located within the Bayport-Blue Point School District.
