Strengths & trade-offs
The Connaught
Strengths
- The Connaught Bar's trolley-side martini and deep vermouth selection
- Staff who learn guest names and preferences within a day or two
- Set back from the street on its own driveway, unusually quiet for central Mayfair
- Strong in-house dining across Jean-Georges and Helene Darroze
- Suites like the Elizabethan junior suite stand well above entry-level rooms
Trade-offs
- Entry-level rooms run small and vary in quality between renovated and older floors
- A strong floral scent in the lobby bothers a real share of guests
- No seating at the Connaught Bar itself, awkward for solo drinkers
- Occasional lapses in front-of-house manners despite the overall standard
The Chancery Rosewood London
Strengths
- Joseph Dirand's residential-feeling suites with walnut, brass, and rare green marble baths
- Rare 25m pool and expansive underground Asaya spa for central Mayfair
- Standout F&B lineup including a Ginza-style Michelin omakase and the destination Eagle Bar
- Dramatic brutalist-to-warm transformation of the former US Embassy building
- All-suite format delivers genuine space even in entry-level categories
Trade-offs

- AC and plumbing noise issues reported in some suites
Scoreboard
| Dimension | The Connaught/ 20 | The Chancery Rosewood London/ 20 |
|---|---|---|
| Tier | Fat Legend | Fat Approved |
| Overall Fat Score | 18+1.5 | 16.5 |
| Service | 18+3 | 15 Named staff like Abdullah and Mario earn real praise, but multiple stays log recurring slow room service and AC problems that a single standout doesn't offset. |
| Design | 16.5 Dark wood, four-poster beds and a newly redone Elizabethan junior suite draw praise, but entry-level rooms are small and one guest called a room old and musty. | 18.5+2 The former US Embassy conversion pairs a Portland-stone brutalist shell with walnut-and-suede interiors, and even entry suites read as spacious by London standards. |
| Location | 18.5+0.5 Tucked off the street down its own driveway in Mayfair, with Bond Street shopping and Hyde Park within walking distance and no traffic noise from outside. | 18 Grosvenor Square puts you in Mayfair without the Bond Street crush, an easy walk to Mount Street and Berkeley Square. |
| Dining | 18.5+1.5 The Connaught Bar's trolley-side martini, breakfast at Jean-Georges and dinner at Helene Darroze all get singled out as some of the best eating and drinking in the city. | 17 Serra and the Eagle Bar get real enthusiasm for food and views, but the minimum spend and pricey, underwhelming cocktails at the Eagle Bar are a recurring gripe. |
| Wellness | 14 The Aman Spa gets a specific mention for working out travel stress, but multiple people note the spa itself is small and it is not why anyone books this hotel. | 17.5+3.5 The spa and pool get called some of the best in London, though families should know under-18s are barred from the gym and treatments. |
The Verdicts
The Connaught
The Connaught costs a genuine splurge, and what arrives for it is one of the most complete hotel experiences in London: a £30-plus martini poured tableside from a trolley, breakfast at Jean-Georges, dinner at Helene Darroze, and a Mayfair address tucked down its own driveway so nothing outside is louder than the doorman. People who've stayed at Claridge's the night before keep saying the Connaught is the one that actually stops them, not the grander lobby next door. The staff learn names fast: guests report being greeted by people they hadn't formally met by their second day, and one review mentions a doorman who'd worked there 42 years.
It isn't flawless, and the flaws are worth pricing in rather than ignoring. The entry-level rooms are small by five-star standards and some guests find the recent redecoration heavy and masculine rather than warm; one long-time regular called her room old and musty. The lobby's floral scent bothers a real number of people, enough that a couple traveling with kids chose to stay elsewhere after smelling it. And service, while excellent almost everywhere else, isn't bulletproof: one visitor got laughed at by a doorman over something as small as a phone charge, and another longtime regular was asked to leave over a takeaway coffee, an incident a manager apologized for but couldn't undo. The bar has no seats, which matters if you drink alone.
Book it for the food and the bar more than for the room itself, since the suites vary more in quality than the public spaces do. First-timers should ask for a recently renovated room rather than assume consistency; solo drinkers who want a stool might prefer somewhere else. For everyone chasing that specific old-Mayfair mood, with staff who remember the mango you like by day two, nothing else in the city does it quite this well.
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.
