Upstairs, the light-filled primary suite boasts a private balcony, two walk-in closets, and a six-piece ensuite with dual washrooms and a central walk-through shower. Two additional bedrooms, each with a walk-in closet and ensuite, along with a well-appointed laundry room, complete the second floor.
