Our favourite rooms
Every room is effortlessly elegant, with the Mayfair Suite affording particularly inspiring Mary Poppins chimney views, but it’s Antony Gormley’s stayable sculpture, ‘Room’, that steals the spotlight. From the outside, the unmistakable stainless steel cubist figure of a man clutching his knees towers over the Beaumont’s entrance. Inside, ascend the chapel-like steps from its white marble-lined bathroom and you enter a 10m-high asymmetric chamber encased in fumed Black Forest oak. Light, should you want it, pours naturally through a shuttered window, otherwise it’s all about embracing the ‘sculptured darkness’ that your eyes (eventually) adapt to. If you’ve ever fancied holing up in the remotest of Alpine cabins or Zen retreats, but don’t fancy the hiking or vows of silence, this is for you. As well as getting artsy kudos, all guests receive a souvenir hardback book, signed by Gormley.
There's a diminutive art-deco hammam and spa with a round, marble plunge pool, a warmed-marble relaxation slab, two treatment rooms and a relaxation area. Choose from classic hammam treatments, facials, and massages, or book an appointment with an osteopath to get to the root of your aches and pains.
A satchel’s worth of PG Wodehouse, Virginia Woolf and Agatha Christie should get you in the mood for some High Society hijinks. If there's no room in your carry-on for your favourite tomes, worry not: each room has a stash of London-worthy reading.
The ground floor restaurant and public bathrooms, and four specially adapted rooms, are all accessible to wheelchair users.
There’s definitely a grown-up atmosphere, but children of all ages are welcome, with babysitting available for £8 an hour if you book one day in advance.
There’s a strict zero landfill policy, a glass imploder for more efficient bottle recycling and a green roof with a herb garden for the chefs and a beehive to encourage pollination.
