Our favourite rooms
The Knightsbridge Suite is the hotel’s showpiece, with a vast raised bed (complete with sumptuous upholstered headboard) – all topped with a massive wrought-iron chandelier that hangs in front of the fireplace. Deluxe Double 209 looks out over the rooftops of Knightsbridge and the iconic (but inexplicable) Harrods chimney. As you’d expect from Kit Kemp, all rooms are individually and lavishly designed, with running themes including tailor’s dummies, oversized headboards and artworks of Peter Clark’s West Highland Terrier (a nod to nearby Harrods).
Bring a credit card with plenty of headroom and a bag with space to stash – Knightsbridge is the motherland of luxury shopping. Actually, forget the bag, Mulberry’s at the end of the street.
Small dogs are welcome to stay free – just let the hotel know in advance. See more pet-friendly hotels in London.
Baby cots are free; extra beds for older kids are £60 a night. Babysitting can be arranged with a local nanny for £8 an hour (four-hour minimum) and £10 taxi fare.
Knightsbridge has a recycling programme in place and uses environmentally sound products wherever possible.
