“Rejuvenate at Aire Ancient Baths. It’s like an underground temple to relaxation.”—Zach, Tribeca
Lit by candles flickering from terra-cotta lanterns, this Spanish-imported spa offers calm and relaxation away from its bustling downtown neighborhood. Only 15 people are allowed in at a time to take advantage of the six thermal baths, which range from 100-plus degrees to 46; the space also includes a salt water pool, steam room, and eucalyptus-infused aromatherapy room. The experience is co-ed and swimsuits are required; we recommend adding a massage for extra relaxation.
