Nestled on a quiet cul-de-sac in Holtsville, 3 Mary Lu Drive is a beautiful center hall colonial. Set on an expansive landscaped and fenced-in property the home offers 4 Bedrooms, 2.5 baths and a two car attached garage. From the front porch as we enter the home, we're greeted by the warmth of the entry foyer. To the right of the entry foyer is the formal living room and to the left is the formal dining room. Moving along the porcelain tiles in the hallway we come to the tastefully updated eat-in-kitchen with stainless steel appliances and quartz countertops. The first floor also has a sitting area, study/den, a half bathroom, coat closet and utility closets. From the sitting area on the first level we see sliding doors which take us to the backyard. We can go to the second floor from two different sides of the home. The staircase in the entry foyer takes us to the magnificent double-door entryway to the primary bedroom ensuite which hosts the primary bedroom with its sitting area, primary bathroom and closets. Down the hallway from the primary bedroom ensuite are three additional bedrooms and a hallway bathroom, offering plenty of space for family and overnight guests. The stairs next to the den/study area takes us upstairs to the recreation room where beautiful and fun memories are waiting to be created. We can enter the backyard from the double doors near the sitting area. The idyllic, large and levelled backyard has apple trees, an above ground pool with surrounding decking, a large patio, a gazebo and a shed. The backyard is like a canvas where the current beautiful painting can be expanded to suit the tastes of the new owners.
