You may know the Experimental Group for its excellent Cocktail Clubs in London, Paris and New York, but its debut hotel, in one of Covent Garden’s prettiest streets, also deserves praise. The 18-room property links two townhouses, and design details feature brushed-aluminium armchairs, patterned carpets and bathrooms with pastel-pink walls and monochrome floor tiles. There are beauty products by Malin + Goetz, John Masters Organics and Ren, and more treats in the minibar, such as selections from the Scotch Malt Whisky Society and Sipsmith. The playful ambience continues in the hotel’s two-storey restaurant, where dishes are artfully composed by the Michelin-starred chef Ollie Dabbous. From £250 a room a night (020 3794 5313; www.henriettahotel.com).
