The Opposite House is a striking design hotel in the buzzing Sanlitun district, housed behind a green glass facade by architect Kengo Kuma. Its light-filled atrium, contemporary art and minimalist rooms with oak floors and deep soaking tubs set it apart from Beijing’s grand traditional hotels. A stainless-steel pool, spa and acclaimed restaurants add to the appeal, and the location places guests among the city’s best shopping, dining and nightlife.
