Caldea's adults-only space boasts a bunch of thermal water experiences and highly specialised treatments, in an exclusive space that's designed to be as bliss as possible. Bathe yourself in the 33°C waters, which are loaded with sulphur, minerals and sodium, all of which are believed to have healing, decongestant and antiallergic properties – how's that for a pampering? Just remember to stick to the entry times you book – you won't be able to visit the spa if you're late.
