Side by side The Berkeley vs The Emory

The Berkeley is the old-money sibling of the Maybourne group, and it still runs like one: doormen who walk first-timers through the bars unprompted, a concierge team that tracks down a lost purse from a taxi by the end of the day, a director of guest services who hands over the Knightsbridge Pavilion suite when a family's room isn't ready. For £1,000-plus a night, that kind of recovery is what you're actually paying for, not just the Cedric Grolet pastries at breakfast (genuinely worth the detour) or the rooftop pool that turns into the best seat in Knightsbridge on a clear day.

It isn't flawless, and the flaws cluster in predictable places. The mini-bar isn't complimentary despite marketing copy that implies otherwise, and more than one guest has walked into a surprise few-hundred-pound bill at checkout. The rooftop pool and bar get genuinely overwhelmed in a heatwave, with hour-long food waits and nowhere to sit, and at least one family was turned away from the indoor pool outside restricted hours with no warning given in advance. One guest described a sharp service dip after a general-management change, pasta mix-ups and inattentive pool staff where there used to be none — worth flagging, though most recent reports still describe the old standard holding.

Book it for the Hyde Park-adjacent location, the Surrenne spa, and a front-of-house team that still remembers names on a second visit. Families do fine here if you confirm pool hours and the mini-bar policy before you arrive; travelers chasing a quieter, more private version of this same ownership group might prefer the newer Emory next door. For the full old-school London hotel experience, with a church view and a proper afternoon tea, this is still one of the better bets in the city.

The Emory is Maybourne's one real departure from the Claridge's/Connaught script: Richard Rogers' glass box across from Hyde Park, 61 keys, all-suite, barely a lobby, sharing a spa and rooftop with The Berkeley next door. Rooms opened around £1,600 a night and the entry Courtyard Studios still sit near that, which buys floor-to-ceiling glass, a stocked-free minibar, a Cédric Grolet pastry on arrival, and Surrenne downstairs. The Tracy Anderson studio and the snow shower come up before anything else, and one guest who stayed five months called it the best spa experience of a very long trip.

This isn't a hotel that performs the same on night one as it does on night five. That same long-stay guest tracked their own housekeeping scores and found mornings ran measurably better than afternoons, and said outright that a one or two-night stay is too small a sample to judge the place fairly. Shorter stays back that up: a slow check-in, no manager on hand when something goes wrong, a "suite" facing a neighbouring building with the curtains stuck shut for lack of any view. The website oversells too: the welcome champagne, the unpacking service, the non-alcoholic beer add-on don't always show up as promised, which reads less like malice than a property still smoothing its edges two years in. A few guests have also flagged there's no concierge on-site for basics like booking a car, so you're sent next door to The Berkeley.

Book it for the design, the spa, and the quiet if you can give it three nights or more and shrug off an off moment; it isn't built for a single-night stopover. Give it three nights and the butlers, the glass, and Surrenne make the case themselves.
