★★★★★ 4.2 guest rating 21 Piccadilly, Westminster Borough, London, W1J 0BH, United Kingdom

An Edwardian landmark on Piccadilly, The Dilly fuses neo‑Baroque grandeur with contemporary British design. Bespoke rooms, a glass‑roofed Terrace and a subterranean health club—home to one of central London’s largest indoor pools—deliver refined, city‑centre luxury.

Historical building / heritage architecture Housed in a Grade II‑listed Edwardian/Neo‑Baroque building originally opened in 1908 (several event spaces including the Oak Room and Georgian Suite retain listed features and heritage décor).
Prime location (landmark adjacent, riverfront, iconic neighbourhood) Central Piccadilly address (21 Piccadilly) — a two‑minute walk from Piccadilly Circus and positioned in London’s West End with immediate access to theatres, shopping and major sights.
Panoramic or landmark views Terrace and Terrace at The Dilly offer outdoor terrace seating and views across Piccadilly and the central London skyline; the glass‑arched canopy creates a light-filled dining space with city vistas.
Art or curated design collection Refurbishment features a distinct curated design scheme (Aspinall Creative Design) with prominent contemporary art, bespoke interiors (Farrow & Ball colours cited in reviews) and curated floral installations.
