Traditional in London

London's oldest luxury hotel — 13 connected Georgian townhouses on Albemarle Street, a Michelin-starred Charlie's by Adam Byatt, and Rocco Forte stewardship.

The only hotel ever granted a royal warrant — fourth-generation family-owned in Belgravia, and the address that hosted Catherine Middleton the night before the wedding.

The Oetker Collection mansion at Hyde Park Corner — Regency interiors, a personal butler in every room, and Céleste under the cupola.
