Description

The Hartley Jazz Club. London, England. "An Evening Worth Remembering." Tucked away beneath the city's restless streets, The Hartley Jazz Club lives in the glow of deep red lights, quiet conversation, and the sound of timeless jazz drifting through the room long after midnight. Inspired by the character of London's late-night music scene, Hartley was created as a place where style, music, and atmosphere meet beneath one roof. From smooth melodies to crowded evenings around the bar, every corner of the club was built to capture the elegance and charm of a classic London night. Whether you're here for the music, the company, or simply the atmosphere — welcome to Hartley. © 2026 Hartley Jazz Club

3 measurements spanning 77 days, net +8. Dots are measurements; the straight line between them is drawn to join them, not to claim we know the path taken in between — snapshots are recorded only when a count changes, so gaps mean “no change observed”, never “interpolated”. The vertical axis spans 8–18 and does not start at zero.
