On Whitehall, Raffles London at The OWO occupies the restored former Old War Office opposite Horse Guards. Its 120 rooms and suites combine Edwardian architectural details with interiors by Thierry Despont, while outlooks vary between Whitehall, courtyards and the London skyline. Dining ranges from Mauro Colagreco’s Mediterranean menus to modern Japanese cooking at Kioku by Endo, supported by several bars and lounges. The Guerlain Spa extends across four floors with treatment rooms, a 20 metre indoor pool, vitality pool, sauna and steam rooms. Hotel guests may use its gym at any hour. Westminster Abbey, Trafalgar Square and St James’s Park are all close by on foot.
