About this home

Step into your dream penthouse in the lively Bay State Commons of downtown Westborough! This sunlit, open-concept gem features 2 bedrooms, a flexible den, and 2 full baths, offering the perfect blend of comfort and style. Enjoy the ease of central air conditioning and in-unit laundry, plus the luxury of 2 private parking spaces. With soaring ceilings and expansive east-facing windows, this space is awash in morning light, creating a warm and inviting atmosphere. The primary suite is a serene escape, complete with two closets and an en-suite bathroom featuring a relaxing soaking tub and separate shower. As part of a professionally managed elevator building, you’ll be steps away from local favorites like Roche Bros., Panera Bread, and Ted’s Montana Grill. With downtown dining, the public library, and Westborough High School just around the corner, convenience is at your doorstep. Plus, enjoy the beautiful Bay State Green park right across the street, perfect for relaxation and play.
