Intimate and elegant, this boutique hotel in a residential street near the Circus occupies three 1772 town houses built by John Wood the Younger for the marquis of Queensberry. It's a perfect marriage of chic sophistication, homey comforts, and attentive service. Renovations have preserved the Regency stucco ceilings and cornices and marble tile on the fireplaces, and each room is individually decorated in contemporary style. Four secluded, terraced gardens invite a summer aperitif, and downstairs is the excellent semiformal, understated Olive Tree restaurant. Pros: efficient service; good location; comfortable accommodations. Cons: some street noise; no tea/coffee-making facilities in rooms.
