There is a certain kind of traveller, somewhere north of 30, who has quietly outgrown the hotels designed to flatter them. They do not want a lobby that doubles as a nightclub, nor a minibar of Pringles and miniature gin they will never open. They want clean design, a proper gym, water they can actually drink from a tap, and a bed that makes sense of a day spent covering ten miles of London pavement. For that traveller, 1 Hotel Mayfair may be the most precisely calibrated hotel in the capital.

Opened in July 2023 as the first European outpost of Barry Sternlicht’s nature-led 1 Hotels brand, the property occupies a commanding position on Mayfair’s Berkeley Street, two minutes from Green Park and Piccadilly. The brand, founded on the idea that luxury and sustainability are not opposing forces, now stretches from Brooklyn to Hanalei Bay, with Melbourne, Copenhagen and Seattle recently added and Crete, Austin, Paris (by Kengo Kuma, no less), San Miguel de Allende and Riyadh in the pipeline. Mayfair is its statement of intent for Europe, and it lands.

Location – 10/10

You will struggle to find a better-connected address in London. Berkeley Street runs directly off Piccadilly, which means Green Park is a two-minute walk, The Ritz is essentially next door, and Bond Street, Berkeley Square, the Royal Academy, St James’s and the West End theatres are all within a ten-minute radius on foot. This is the rare Mayfair address that is genuinely walkable to almost everything you came to London for, without the traffic-clogged compromise of Park Lane or the tourist crush of Piccadilly Circus. Step out, turn left, and you are in the park before your coffee has cooled.

Design & Public Spaces – 9/10

The building itself is a quiet triumph. Rather than demolishing and starting again, the developers retained around 80 per cent of the existing 1970s structure (the site was, improbably, once a Holiday Inn), rebuilding to BREEAM Excellent standards and adding two new floors of light-flooded suites up top, including the largest one-bedroom penthouse in Mayfair. More than 500 square metres of living green walls climb the exterior, irrigated by rainwater collected from the roof, and the once-forgotten service lane between Berkeley Street and Dover Street has been re-cobbled, pedestrianised and gifted back to the neighbourhood as Dover Yard.

Inside, the lobby is the hotel’s thesis in miniature: pale wood panelling, hand-chiselled stone, clean Scandinavian-lined chairs arranged in conversational clusters, and, in winter, a fireplace that makes the whole space feel properly hygge. Plus a complimentary selection of farm fresh fruit for guests checking in. People are dotted about working and chatting all day, but this is emphatically not an ‘Ennismore’lifestyle hotel’-style co-working scrum of laptops and oat flat whites. The crowd is a step further along in life, financially and otherwise, and the room reflects it: calm, assured, polite. Neighbours, the lobby café, handles ethically sourced barista coffee by day before rattan panels slide across and it softens into an aperitif bar by evening.

Rooms – 9/10

The rooms are precisely what you want to come back to after pounding London’s streets: a palette of soft creams, whites and warm browns, sustainably sourced British oak underfoot, organic mattresses on deeply comfortable beds, and a small moss wall bringing the brand’s biophilic promise into the room itself. Bathrooms are lined in Welsh slate, with deep tubs made for post-museum recovery, Toto toilets, and refillable Bamford toiletries in generous dispensers.

Then there are the details that this hotel’s target guest actually notices. Filtered water taps in every room, with glass carafes, meaning not a single plastic bottle in sight. A minibar stocked with things you might genuinely want rather than the usual graveyard of chocolate, crisps and spirits nobody touches: as habitual minibar abstainers, we found ourselves browsing with real interest, and left several bags of artisan health snacks and elixir powders lighter. A yoga mat waits in the wardrobe; occupancy sensors quietly manage lighting and airflow when you step out.

Our suite was generous without being cavernous, every corner earning its keep, with clever partitions that close the lounge away and let the bedroom draw in around you at night. Even the room service menu shows the same discipline: exactly what you want, and nothing more. It is the rare hotel room where the sustainability story and the comfort story are the same story.

Food & Drink – 9/10

Dovetale, the ground-floor restaurant from two-Michelin-starred chef Tom Sellers (of Restaurant Story), is the headline act, and deservedly so: seasonal, produce-led European cooking with a raw bar, dishes from the grill and a tableside Knickerbocker Glory trolley that has become something of a London signature. But the quieter achievement is Dover Yard, the bar and lounge overlooking the botanical courtyard, backed by Yorkshire dry-stone walls and furnished with pieces by Katie Walker. It is busy all day, and crucially not just with guests: office workers, residents and locals treat it as their own, which is exactly the point. Few Mayfair hotels have embedded themselves in their neighbourhood this convincingly, this quickly.

We will say it plainly: this may also be the best hotel breakfast in London, and it holds its own against any city we know. Served in a bustling Dovetale, thick with locals at the weekend, breakfast during our stay was entirely inclusive: no supplements, no add-ons, no bill presented at the end. The generosity is the luxury. Bone broth, breakfast wraps, granola and chia bowls, full English with every side you could want (and as many as you like), excellent coffee, fresh juices and ginger shots: everything the modern traveller actually eats, done properly, in abundance. Despite the weekend crowds, the impressively on-it team will always find you a seat, inside or out on the terrace. If breakfast is the truest measure of a hotel’s confidence, this one is supremely confident.

Wellness & Fitness – 8/10

The Field House, the first-floor gym, is one of the best hotel fitness spaces in central London: fully kitted out with Technogym equipment, custom programming, and enough room to do a genuine session rather than a token one. The adjoining Bamford Wellness Spa delivers the brand’s organic, botanical treatments in serene form. Our one wish, and it is the thing keeping this hotel from a perfect wellness score: a sauna or steam offering. For a property this fluent in recovery and wellbeing, their absence is felt, and adding them would elevate the offering to another level entirely.

Verdict – 9/10

1 Hotel Mayfair is the hotel London’s design-literate crowd has been waiting for: Scandinavian calm in one of Mayfair’s best positions, a sustainability model with real substance behind it, a gym worth packing kit for, and a breakfast that borders on an event.
