"Housed in an excavated cellar, this Arabic-style hammam occupies a candlelit, beautifully restored space. Work your way through a series of hot and cold baths before settling in for the signature Kessa-glove scrub and massage combination treatment—a godsend when the sensory overload that is Madrid gets to be too much. The communal baths and tea room (the mint tea here is kind of legendary) are unisex, so you’re welcome to chill out in the company of your S.O. between treatments—so long as you keep to the strict no-talking rule.
