"Housed in a striking Grade II-listed neoclassical building, this Mayfair hotel channels prewar glamour with warm public rooms, cherrywood paneling, oil paintings and more than 1,500 artworks; its 50 rooms and 22 suites favor art-deco touches like bronze mirrors and silk curtains, and suites offer living rooms, libraries and terraces. Recent refurbishments added an outdoor terrace, a new Mayfair Suite and an enlarged spa, while dining and drinking highlights include an intimate 30-seat American-style cocktail bar focusing on bourbons and whiskies and a classic clubby grill—plus a complimentary emissions-free chauffeur service for nearby trips." - Jennifer Flowers, Annie Fitzsimmons, Katherine LaGrave
