"Built inside a former tram depot beside Milan’s old Spanish walls, this visually striking spa centers much of its experience underground amid stone caverns that house thermal pools, steam rooms and saunas. Standout features include a glass-walled bath set around ancient ruins, an eye-catching tramcar sauna and a multi-sensory “cinema” pool where projections, indoor rainfall and storm sounds create immersive aqua therapy. As evening falls, guests can partake in an aperiterme ritual — enjoying a spritz in their bathrobe." - Low Shi PingandCraig Sauers
