I think the spa is small, it has everything you need but size. Treatments are good and service is good. Given its a old London building they have squeezed a lot in but if more than a couple of you it does seem small in the changing area.
Venue is great and works really well for this offer of treatment and private use of spa for 2. The therapists offer a small selection of treatments but all performed to a high standard.
A lovely, relaxing environment and perfect way to spend 3 hours away from the hustle and bustle of outside. I have already booked another experience at this spa.
