In the 1960s, the imposing US embassy building on London's Grosvenor Square was a symbol of diplomatic power and Cold War secrecy. Today, that same Grade II-listed building has been reborn, not as a fortress of statecraft, but as a temple of luxury hospitality, recently named the world's best new luxury hotel.
From Diplomatic Hub to Five-Star Haven
Following the embassy's relocation in 2017, the iconic site underwent a monumental eight-year, £1 billion renovation masterminded by renowned British architect Sir David Chipperfield. The highly anticipated result, The Chancery Rosewood, opened its doors in September 2023. The transformation is profound: where security once stood guard, door staff now welcome guests into a grand entrance hall, replacing an impenetrable aura with one of sheer glamour.
The hotel's 144 all-suite accommodations start from £1,640 per night this Christmas, soaring to £26,100 for the lavish residence-style House suites in December. The interiors feature a palette of warm tones with gold trimmings, and the floor-to-ceiling windows offer panoramic views across the capital. The building's history is preserved in details like the iconic eagle sculpture, which still overlooks the greenery of Grosvenor Square.
Opulent Amenities and Culinary Stars
The hotel's offerings are designed to impress. The Asaya Spa boasts a majestic 25-metre swimming pool, a fitness centre, and five treatment rooms. For dining, there are eight restaurants and bars, including Carbone, the first European outpost of the famed New York Italian eatery, and Tobi Masa, marking the London debut of celebrated Japanese chef Masayoshi ‘Masa’ Takayama.
The crown jewel for many is the Eagle Bar on the rooftop, featuring a wrap-around terrace, an impressive cocktail list, and a curated music programme. For a more casual bite, GSQ delicatessen offers coffee, pastries, and snacks with a terrace on the square.
A Blend of Acclaim and Criticism
Despite the plaudits from Luxury Travel Intelligence and praise from publications like the Financial Times, which dubbed it 'the hottest reservation in London', guest reviews have been mixed. The hotel's TripAdvisor rating stands at a modest 3.4, with several visitors criticising inconsistent or poor service, contrasting sharply with the premium price tag.
However, many other guests have raved about the experience. Positive reviews on platforms like Booking.com, which rates it 8.7, describe it as 'exceptional' and 'just beautiful', praising the spacious suites, exquisite spa, and prime Mayfair location.
Ultimately, The Chancery Rosewood represents a unique fusion of profound history and ultra-modern luxury. As the Financial Times noted, this 'cold war monument has finally been returned to the public' – albeit at a significant cost, and with a service standard that is still being refined in the eyes of some.
