About the project

The St. Regis London marks the St. Regis brand's debut in Mayfair, a transformation of the former Westbury Mayfair hotel at the corner of Bond Street and Conduit Street in the City of Westminster. Owned by Cola Holdings and operated by Marriott International under the St. Regis flag, the 193-key luxury hotel includes 66 suites, with interiors that draw on Savile Row tailoring, the fashion houses of Bond Street and the neighborhood's galleries and auction houses, arranged around an intimate central courtyard. Dining is led by Le Perroquet, an all-day French brasserie from chef Daniel Rose, joined by a lobby bar, while the signature St. Regis Butler Service, a full-service spa and a fitness center round out the offering.
