4. Mandarin Oriental Hyde Park
After a fire in June 2018, this local stalwart reopened last April. Gone are the heavy curtains and throws. Instead, everything is lighter, fresher—even the marbled lobby. Rooms have been painted a pale gray, and had gold lampshades added. The carpets have been replaced with wooden doors, and there are little libraries curated by beloved bookseller Heywood Hill. Still, the best rooms are the Hyde Park-facing ones, where the sound of the Household Cavalry clip-clopping past is better than any morning alarm. Artist Leah Wood has revamped the Butterfly Terrace with floral art; in the ballroom—where Queen Elizabeth learned to dance—every inch of gold leaf has been restored; and both Bar Boulud and the molecular Dinner by Heston Blumenthal are packed every night.
