The Berkeley

What the classifiers highlight

In Knightsbridge near Harvey Nichols and Harrods, this hotel held London's only rooftop pool for years, a heated one facing Hyde Park with striped loungers and an open-air bar that reportedly counts Madonna among regulars. Forbes rates it Five Stars and highlights the four-floor Surrenne spa; MICHELIN's Two Keys note the summer terrace's Côte d'Azur mood.
