Rosewood
The Chancery Rosewood London
The Chancery took the old US Embassy on Grosvenor Square, a brutalist Portland stone block Mayfair had learned to look past, and turned it into the most architecturally confident hotel London has opened in years. Joseph Dirand's suites run genuinely residential, walnut and brass and rare green marble baths, with even the entry Junior Suites hitting 570+ sq ft. The 25m pool and Asaya spa below ground are a real point of difference in a city where most luxury hotels can't spare the basement for it, and the Ginza-style omakase plus the Eagle Bar (that salvaged B-52 eagle now sitting over two new penthouse floors) are destination-worthy on their own, not add-ons. The service is uneven, and it's been uneven since the September 2025 opening, not just in the first nervous weeks. One guest got a butler who gave an unforgettable private tour and a manager who remembered a child's name; another, a week later, got an AC unit switching itself on at 3am, an afternoon tea where the tea itself never arrived, or a concierge quoting £1,200 for a tour bookable elsewhere for £250. Several stays land on the same description without prompting each other: reactive rather than anticipatory, fixed after the fact rather than caught before it happens. Nearly a year in, that's not opening jitters, it's still the pattern. Worth pricing in, not worth avoiding the hotel over. Book it for the design, the suites, and the spa: nothing else in Mayfair offers this much space and wellness for the money. Go in knowing service is a dice roll, not a guarantee — if flawless, intuitive staff matters more to you than anything else, Claridge's or the Connaught still deliver that more reliably. For the building and the suite alone, this earns the trip.
