Spanish export Grupo Aire hosts bath time in Tribeca. Circa-1883 cast iron building ancient by Manhattan, if not Spanish, standards. A pretty penny spent, evident in the immaculate build-out across three levels. Steam baths intensified with aromatherapy, jet-propelled fountains, and cold, hot, and warm pools. Spa services and fresh organic juices. If you can’t get rejuvenated here, it may be time to lay off the speed.
