The weather can be challenging, and as a long-term resident I concede the atmosphere is often miserable, but when it comes to delivering an incredible high-end hotel experience few cities compare to the colour and flair of London. Already unquestionably home to some of the world’s best urban properties, this autumn brought the long-long-awaited debut of The Chancery.
Rosewood Hotels’ second address in the city, it’s the latest in a slew of billion-pound hotel openings that have gone all out to redefine the levels of luxury on offer here. With the doors now finally open, you can see where they spent the money: pass the Portland stone facade of this Modernist marvel and you’ll enter a realm that’s the epitome of no-expense-spared. Exceptional attention to detail, world-class amenities and genuinely tasteful suites have combined here to create something that feels really special.
In Short:
A longstanding London landmark given a new lease of life, and undoubtedly one of the most glamorous hotels in the city.
The Location
Postcodes don’t come more aspirational, or pricey. This is prime London real estate, with Hyde Park just moments away and Selfridge’s and Bond Street’s boutiques within skipping distance. Nearby Elizabeth Line and Tube services can whisk you to the city’s most famous cultural attractions, or it’s a 20-minute walk to enjoy the exhibitions at either The Wallace Collection or the Royal Academy.
The Background
Rosewood’s debut in London came over a decade ago, when the first Rosewood London opened in a particularly beautiful listed building in the somewhat questionable location of Holborn - though it’s minutes from the British Museum, this otherwise overlooked district doesn’t hold the cachet of the capital’s more chichi neighbourhoods. Then, somehow, the hospitality group got hold of one of the last prime plots to be had in Mayfair, tied with Knightsbridge for first place as the capital’s glitziest, most glamorous district.
The opportunity arose because the city’s longstanding American embassy on leafy Grosvenor Square was being relocated and suddenly its building, an austere, modernist concrete landmark designed by Finnish-American architect Eero Saarinen in 1960, was empty. With Qatari backers, a phenomenal budget and oversight from British architect Sir David Chipperfield, Rosewood has been very busy over many years transforming it into what it hopes will be regarded as the most lavish luxury hotel in the city - a title for which there’s very stiff competition.
To that end, they’ve dug deep (figuratively, literally) to create something really distinct and incredibly decadent. Though the original building’s facade was maintained, its interior is almost entirely reimagined and reconstructed. Now billed as an all-suite property, it delivers some of the most expansive accommodations in London, a swathe of swish new restaurants and bars and first-class wellness facilities. Given the original embassy building was strictly off limits to almost everybody, and its beauty remained obscured by security cordons and barricades, Londoners have been especially eager to explore this property - it’s undoubtedly been London’s, and, really, the country’s, most anticipated hotel launch of the year.
The Guests
You’re right in the middle of Mayfair and within one of the priciest hotels in the country, but the crowd’s still a nice reflection of this eclectic city. With Rosewood’s headquarters in Hong Kong, expect to encounter big spenders from Asia over on shopping jollies alongside heavy hitters from the world’s creative industries - Rosewood does a good job of feeling a bit more progressive than a lot of its competitor luxury-hospitality companies - alongside locals who’ve been reading all about this launch for years and have dropped in for coffee or afternoon tea.
The Rooms
Though I question whether junior suites are proper suites at all (given their lack of segregated living area), from its entry-level category up, accommodations at this hotel are exceptional.
Mad Men-style interiors and surprisingly bucolic views - through floor-to-ceiling windows, they might look towards the Grosvenor Square canopy, allotment-style planters laden with British wildflowers, or on to the lovely higgledy-piggledy townhouses that line Mayfair’s sidestreets - make the spaces feel really homely, something that’s compounded by occasional surprises and treats. The minibars are stocked with lots of delicious, imaginative and complimentary British goodies; bathrooms include airline-style amenity kits to keep, and the slippers are so comfy, chic and inconspicuous I happily kept them on as I plodded through the hotel and hung out in the lobby.
Still, at this price point, it’s reasonable to have sky-high expectations - the one omission that stood out to me was the lack of a Japanese-style electric toilet, something that was once uncommon in London but has recently become pretty much de rigueur for the city’s newer, fancier openings.
The Restaurants
With Mayfair already home to some of the most extravagant and hyped restaurants in the city, The Chancery’s F&B offering faces some stiff competition. It’s a good thing for guests, who can zig-zag from airy all-day tea lounge Jacqueline to golden-hued Tobi Masa (an offshoot of chef Masayoshi Takayama’s three-star Masa in New York City) and up to the rooftop Eagle Bar, where the terrace is guarded by the sculpture of a gilded eagle, big as a Cadillac and crafted from the remnants of a B-52 bomber. The offering is exciting, and complemented further by the recent opening of Carbone within the same building, though for me the hotel’s F&B offering still lacks some of the alchemy I encountered in the rest of the property.
I admired the egalitarian ethos of GSQ, envisioned as a proper, accessibility priced neighbourhood deli where locals can gather for good coffee, sandwiches and pastries, but was less taken with SERRA. The Southern Mediterranean restaurant looks beautiful, but our menu felt a bit unsure of itself and consistently muddled service made it seem as though the venue was still finding its feet.
Wellness & Spa
First things first: city hotels’ basement fitness and spa facilities might occasionally look drab, but here they’re stunning.
The spa team will proudly tell you that their new Artis Luxury line of gym equipment from Technogym, in caramel tones rather than the brand’s standard black finish, is partially made from recycled materials, and the 25-metre pool set in its own silver chamber is slick and serene. But beyond its good looks this is a comprehensive wellness facility (a very small number of locals have been offered the opportunity to be members for about £1k a month so it needs to deliver).
Other amenities include an ice bath, expert facials courtesy of The Taktouk Clinic and a ground-level spa boutique that’s so well curated - almost all its products are sold on an exclusive basis so available nowhere else in the city - that it’s a genuine pleasure to peruse its collections, even for apathetic shoppers like me.
The Staff
Save for the team at SERRA who were surprisingly unsure of what they were serving, staff throughout performed with panache and ease despite the hotel only recently opening. Given the cost of staying here, service is aligned with the tenets of traditional luxury but Rosewood still feels a bit fresher and youthful than many of the long-established hospitality brands - it’s a bit more approachable here than you might expect of some of the other posh hotels in the vicinity.
Sustainability & Accessibility
Extensive behind-the-scenes efforts went into ensuring the building aligns with exacting BREEAM sustainability standards: the BREEAM construction standards provide a framework to deliver high performing and sustainable newly built assets. This impactful project runs alongside the now-expected sustainability initiatives such as no plastic bottles, refillable toiletries, and in this case partnerships with the likes of Fair Shot coffee, which supports opportunities for adults with learning disabilities, and young London creatives show a commendable commitment to supporting the local community.
Wheelchair-accessible suites are available.
How would you describe it to a friend?
In the best possible way, the hotel feels very, very expensive. Fancy without being fusty, a weekend here feels like total indulgence.
