Swim with garden views and soak in the whirlpool; watch the floating world go by on the tidal Qiantang River; visit one of the world’s most famous green tea plantations close by (and try a huge number of varieties in the lounges); and workout in the top class fitness centre at The Azure Qiantang. Dine at Panorama on the 22nd floor and Lan Ting on the 23rd floor, whose glamorous 1920s-era accents create a vintage glamour. Ceilings that mimic the sky, a palette of baby blues and soft taupes and gleaming high-shine floors create a sleek aesthetic.
