Some rooms are designed to be fully accessible for guests with reduced mobility.

Measuring an expansive 81 to 86 square metres (870 to 926 square feet), these are the largest one-bedroom suites in The Beaumont. Each has its own unique layout, but all overlook Brown Hart Gardens. Silks, mohair velvets, bronze detailing and subtle geometric patterns create a calm, relaxing environment for business or pleasure.

The bedroom of this unique suite occupies the interior of a giant semi-abstract sculpture by Antony Gormley, which dominates the entrance front of The Beaumont on Brown Hart Gardens. A dark, mysterious, cave-like space, ROOM encourages its occupants to enter a different state of consciousness, to enjoy at the very least a quiet, meditative pause, a prelude to a good night’s sleep and the chance to withdraw, for a while, from the busy world outside. The wood-panelled bedroom is approached up stairs from the sitting room and the marble bathroom, which are decorated, like all the rooms in The Beaumont, in a soft Art Deco style. The suite also has a large private hallway and a guest bathroom.

This large one-bedroom suite is 91 square metres (980 square feet) in size, making it perfect for entertaining. The comfortable sitting room provides ample space for relaxing, dining and working, while a generous and very private terrace overlooks Brown Hart Gardens and has wide views towards the City of London.

The Beaumont’s presidential suite, which can be extended to include five bedrooms, reflects the glamorous era of the great transatlantic liners of the 1920s and 1930s. It has a delightfully spacious sitting room and a separate dining room seating eight, plus a pantry kitchen and a guest bathroom. The suite features cream lacquer panelling, brass inlaid details and parquet timber floors, while silk curtains, hand-made rugs and period works of art create a discreetly opulent setting.

A relaxed, sophisticated, New York style Grill with a timeless menu of transatlantic favourites, salads, crustacea, grills and steaks, and a big helping of old-world glamour.

The Magritte Bar belongs to the great tradition of American bars that became legendary in London and Paris during the 1920s. Ernest Hemingway and F Scott Fitzgerald would have felt at home in its handsome walnut-panelled, book-lined interior, hung with an eclectic collection of early 20th century paintings, and rare ‘Charlot’ Charlie Chaplin posters, all influenced by the vibrant Parisian art scene of the time.

Jazz, another American import after the First World War and the soundtrack to which the artistic quartiers hummed, is played live on Thursday, Friday and Saturday evenings. The Bar specialises in bourbons, American whiskies and classic cocktails, which are strictly shaken or stirred.

The Cub Room is a relaxing lounge bar reserved exclusively for guests of The Beaumont and their visitors. A perfect private getaway, it is the ideal place to enjoy a cocktail, complimentary coffee and pastries in the morning, or simply to read the papers. An all-day snack menu is served by The Colony Grill.
