Until 2007 when Spa London opened in Bethnal Green, there was no such thing as an affordable day spa in in the capital. A second branch has now opened at Swiss Cottage Leisure centre with a long, good-value treatment menu. Still, for a complete spa day package you're best sticking to this East End original where facilities include steam rooms, Turkish hamam and plunge pools.Treatments range from an Escape in the City Salt Scrub (a 25-minute cleansing that should remove all trace of London grime), to the spa's signature Gym & Tonic in which your body is cleansed, body brushed and exfoliated, before being treated to an aromatherapy massage and warm marine mask. Indulgence without the price-tag.
