"You may think you can’t float but a dip in Aire Ancient Baths’ salt-water flotarium will soon prove you wrong. Book the Aire Experience to enjoy this and five more thermal baths (hot, warm, ice and cold plunges, plus jet pool), as well as an indoor/outdoor pool with a waterfall and a salt-exfoliation station. Exposed brick walls, wooden beams and the highest of ceilings abound in this one-time factory. The baths are lit from below, with flickering candles illuminating the paths between them. Sign up for a full-body massage or a Himalayan salt wrap, or simply waft from bath to bath until your finger pads are good and wrinkled."
