COMO The Halkin, London

What the classifiers highlight

Opened in 1991 as the first COMO property and London's first luxury boutique hotel, this Belgravia address keeps just 41 rooms, thirteen of them suites with marble bathrooms. Forbes notes its Spanish-leaning afternoon tea, croquettes and churros from the Ametsa kitchen, paired with cocktails made using gin from the London distillery Sipsmith.
