On Park Lane, the first Four Seasons outside Canada pairs discreet heritage with luminous modernity. Many of the 196 rooms and suites capture Hyde Park or Westminster, while the glass-walled rooftop spa by Eric Parry Architecture floats above the treetops—treatment rooms reveal sweeping vistas for deeply restorative rituals. Downstairs, Pavyllon London by Yannick Alléno serves impeccably crafted modern French plates; Bar Antoine is a spirited hideaway for storytelling cocktails. Service is hushed and exacting; the setting, minutes from Knightsbridge and the park, feels both central and cocooned. For couples, this is the London classic: polished, poetic, and purpose-built for lingering breakfasts, golden-hour walks, and late-night returns to candlelit calm.
