Fat Score
The Verdict
The Chancery Rosewood has transformed the former U.S. Embassy into Mayfair's most striking new luxury destination. Joseph Dirand's interiors are a masterclass in masculine elegance — walnut, brass, and rare green Indian marble creating spaces that feel both palatial and intimate. The all-suite concept delivers genuine value in a city where space is precious, while the Eagle Bar offers London's most dramatic rooftop views. Service shows occasional growing pains typical of a new opening, but the bones are exceptional: this is David Chipperfield architecture housing one of London's most impressive private art collections, with eight dining venues positioning it as a true neighborhood institution rather than just another hotel.

What People Say
We've tried nearly every luxury hotel in London, and I'm interested to see how Chancery compares to our beloved Lanesborough.
We visit London monthly and always return to Lanesborough because the service magic there is unmatched — genuine, heartfelt interactions that make you feel like family. We're planning to try Chancery next time to see if it can deliver that same level of personal care and attention to detail that makes Lanesborough feel like our London home.
My husband and I tried this brand new hotel for a few days and it was sublime — the spa is immaculate.
The staff at the spa were incredibly kind and helpful, and the pool is so long and beautiful. We had tea instead of wine because they had such an amazing range, and the setting is so comfortable with natural wood, mohair, and natural materials everywhere. My only advice would be proper barista-quality coffee instead of Nespresso, but we're coffee lovers so that's just us.
I celebrated my 40th birthday here and have never experienced this type of hospitality and service anywhere in the world.
They went so over the top making me feel loved and cared for during both my solo celebration and then with my children. I ate and drank at every restaurant and bar — all were excellent. The art collection is absolutely breathtaking, and I spent an entire day at the spa with that massive, well-heated pool. The facial and massage were amazing, and they allow children from ages 4-5 which is great for families.
I stayed for two weeks and every aspect exceeded my expectations — this represents luxury, elegance, and impeccable service.
From the very first moment, the welcome was warm and gracious, truly reflecting the hotel's high standards. Special thanks to Reception Manager Abdullah whose exceptional professionalism made a remarkable difference. Our suites were absolutely wonderful — incredibly spacious, beautifully designed, and stunning. The doormen were consistently kind and helpful throughout our extended stay.
We've stayed at all the top London hotels in the past, and this one now firmly leads the list.
Our room was very large and beautiful, and the hospitality across the board was impeccable. The spa, gym and pool were super luxurious, and the Eagle Bar is a must-visit with stunning Mayfair views and delicious martinis. The afternoon tea was really excellent with a huge collection of exotic teas. We'll definitely be back.
Despite beautiful design, the experience was disappointing especially for families with extremely restrictive wellness policies.
The hotel looks luxurious and modern with high-quality finishes, but children under 18 can't use the gym and there are no spa treatments for kids. Pool access is limited to just two one-hour slots daily, and when we called ahead, none of these restrictions were mentioned. Some staff interactions felt uncomfortable with obvious preference for certain guests over others.
This is a hotel with strong potential but currently falls short of delivering a consistently polished luxury experience.
The hotel is beautifully designed with strong physical standards, but we experienced recurring service issues during our five-night stay. Problems became persistent rather than isolated incidents. Francesco Mbar provided exceptional service that helped offset broader operational shortcomings, but overall it felt like reactive rather than proactive guest care, which isn't what you expect from this caliber of property.
We stayed during New Year's and found this hotel nearly flawless — the design debate comes down to personal taste.
I compared it to Claridges and Four Seasons Park Lane during the same trip, and honestly Chancery held its own beautifully. The building transformation from that ugly Embassy eyesore to this is remarkable. Our Mews junior suite had a balcony and felt enormous for London standards. The Eagle Bar was swamped our first visit but the views are spectacular, and the spa is genuinely luxurious and large.
The John Hay Adams suite absolutely blew me away — this is now one of my top London suite picks.
I sell top London suites including Claridge's Mews Terrace, but this unit was exceptional. The color palette, flooring, and finishes speak for themselves — darker and more masculine than most but flooded with natural light. It sits perfectly between Connaught's masculine vibe and Claridge's airy showiness. My only note is that it doesn't feel quintessentially British, but the suite itself is flawless.
I stayed in mid-September and was genuinely impressed — this is already competing with London's best.
The building has genuine presence, and the renovation is beautifully executed throughout. Our upgraded Mews junior suite was still one of their lower categories but felt large even by non-London standards. The design is definitely modern rather than traditional British, but I loved it. Minor service hiccups like slow room service responses, but the free airport transfers both ways were a nice touch.
I've been waiting eight years for this opening, and the former U.S. Embassy has become something genuinely special.
We knew this brutalist building would be polarizing, but they've kept that Mad Men vibe while making locals feel welcome again. The gold eagle from B52 bombers still dominates, now perched atop two new floors with floor-to-ceiling windows that are absolutely gorgeous. Eight F&B outlets including the first European Carbone feels ambitious, but the four entrances show they're serious about becoming a Mayfair institution rather than just another hotel.
I toured the 99% completed hotel before opening, and David Chipperfield's reimagining of the Eero Saarinen embassy is genuinely impressive.
The brutalist façade is Portland stone, not concrete, and inside the mood completely softens. American walnut and suede throughout, with materials that feel like classic gentlemen's clubs but thoroughly modern. The all-suite concept works brilliantly here — even entry-level rooms feel spacious for London. The location on Grosvenor Square is quiet for Mayfair but still walkable to Bond Street and Mount Street.
