  • Setting The Standard
    Meticulously refurbished with style & imagination this luxury B&B resides on a quiet, historical, tree-lined street in fashionable Dupont Circle near embassy row. Built in the 19th & 20th centuries, The Mansion retains many period details (including original Tiffany stained glass windows) but incorporates into the architectural features all the modern conveniences – including state-of-the art technology.

  • Sumptuous Surroundings
    Ultra-private and secure, we offer a variety of rooms and suites, each individually decorated with fine art, antiques and furnishings purchased from around the world. Dedicated to providing a special experience for every guest we match you with a suite that will fulfill your every desire.

  • No Request Too Large, No Detail Too Small
    Having been a haven for heads of state, writers, foreign dignitaries, business leaders, artists, musicians, scientists, and members of the entertainment industry, we offer privacy, security, distinctive amenities and world-class cuisine, all in an environment that is nothing short of magical.

  • A Strict Mansion Privacy Policy
    We provide the ultimate in privacy and anonymity to all of our guests from the moment they walk through the door, and beyond. We employ a strict, no-tolerance policy that includes never sharing your personal information—even your name—with anyone, before, during or after your stay.

  • Simply put, no one can reach you when you are here, unless you give them your password or your mobile information. Unexpected visitors who come to the door or call for a guest/member/employee, without a password, are told “There is no one here by that name” — No exceptions.

    What happens at The Mansions stays at The Mansion. This is part of our core philosophy and a key reason why the Mansion continues to be a preferred venue for so many private and corporate events over the years.

our uniquely styled suites and residences offer an ideal place to call home while on assignment

90% of what you see in The Mansion is donated by our generous guests to help sustain our programs. We are a unique, eclectic, vibrant, always evolving property, devoted to making dreams a reality. If you love music & the arts, and want a home away from home, this is the place. If you want a plain vanilla hotel, we may not be for you. What happens at The Mansion, stays at The Mansion.
