What visitors say
Third Space City draws members who've left budget gyms specifically for the environment and integrated wellness offering. The pool, sauna, ice baths, and unlimited classes (hot yoga, pilates, sound baths) are well-used; swimming coaching is particularly praised. Staff—especially named PTs and concierge—are consistently described as knowledgeable and welcoming. The changing rooms are spotless and towel service is included. Reviewers cite the facility as a reason to stay in London, though membership is premium and worth it primarily for regular users.
