Occupying the lower floors of Mies van der Rohe's landmark IBM Building on the banks of the Chicago River, this five-star hotel opened in 2013. Rooms are spacious with floor-to-ceiling windows framing river, skyline, or Lake Michigan views, and marble bathrooms with deep soaking tubs and rainfall showers. The Langham Club on the uppermost floor offers butler service, all-day refreshments, evening cocktails and panoramic views. Travelle serves seasonal American cuisine, while the Chuan Spa, indoor pool and well-equipped fitness centre complete the offering.
