Introducing Residence One at 257 Commonwealth Avenue, one of just six residences in a historic, double-wide brownstone in Back Bay. Residence One is a stunning, newly renovated home offering a wonderful opportunity to own almost 2,000 square feet on the beautiful, tree-lined Commonwealth Avenue Mall. The residence combines two bedrooms and two full bathrooms with luxurious living spaces that have been meticulously constructed with unerring attention to quality: Every detail and finish—from the gourmet kitchen to the spa-like baths—is top-of-the-line and befitting of such a fine Back Bay address. Additional features include central air, in-unit laundry, ample storage, and a private entrance. 257 Commonwealth Avenue is a professionally managed, pet friendly building just steps from the fine shops and restaurants of Newbury Street, Prudential Center, and the Charles River Esplanade.
