This young garden-style condo is located on the second floor at Groton Residential Gardens. Building 503 is located far away from the main road. A spacious vestibule and stairs lead up to Unit D. It's more private and quiet here, with pretty views into green space and additional (informal) parking out front. Lovingly-painted and gently-used, this home is in nice condition as it has only been lived-in for two years. Enjoy the sunny and light-filled space, consisting of an open-concept living room, dining room and well-equipped kitchen. A hallway leads to the private back section offering a full bath, laundry, master suite with en-suite bath and second bedroom. A balcony with the utilities and some storage is accessible off the master bedroom. Exterior back stairs lead to the ground floor. Efficient gas heat; central AC a plus in the summer! Let somebody else worry about plowing and lawn care, and enjoy the life style at Groton Residential Gardens!
