The Spa at Charlotte Square sits inside Kimpton Charlotte Square, on Edinburgh's Charlotte Square. Its leisure club combines Technogym equipment, Peloton bikes and free weights with Pilates, HIIT, spin and yoga, while the wet side holds a mood-lit 12m pool, sauna and steam rooms, and a relaxation snug. The hotel also runs Swell, a sound wellness room. Members get 20% off spa treatments Monday to Thursday and 50% off Swell Room sessions.
