With rooftop views, umami-packed bites, and a grand marble bathtub worth writing home about, this hotel is the discreet star of Hanover Square. Walking through London’s historic Mayfair district, I was so taken by the Georgian-style architecture, boutique shops, and adorable cafés that I almost passed the entrance to my hotel. Tucked away in Hanover Square, the 50-room Mandarin Oriental Mayfair, London, which opened in June 2024, is one of those easy-to-miss but instantly unforgettable spots.
