Carlton House (formerly known as the Residences at the Ritz-Carlton) is the Grande Dame of luxury Boston condo buildings. Formerly affiliated with the old Ritz-Carlton Hotel, it now benefits from best-of-the-best hotel services from The Taj Hotel, which purchased the old Ritz-Carlton building.

Carlton House is located at the corner of Commonwealth Avenue and Arlington Street, right across the street from the Boston Public Garden, in the heart of Boston's elegant Back Bay. It sits right near the corner of Newbury and Arlington, at the center of Boston's high-end shopping and dining district. Units here rarely become available, and are highly sought after. Units at the Carlton House have been renovated at various times, so finishes vary.
