On a busy street in Tribeca, candlelit lanterns line the sidewalk leading to a glass doorway that invites you to step out of time. Inside, rough wood and stone lit by a thousand candles suggest you begin to shed civilizing layers, get down to skin and breath. Aire Ancient Baths is a nouveau Greco-Roman bathhouse: a sequence of pools, steam rooms, saunas, and yoga and massage sense riots. It might be heaven. Especially two weeks out from an Ironman training taper. Ancient body wisdom. New York-style. You're welcome.
