For the second year, Fortune partnered with Travel + Leisure to survey readers on their tastes and habits while traveling for work. They were asked to rate their favorite hotel brands on customer service, room design and amenities, business and meeting facilities, value, and loyalty programs.

This year, readers named The Peninsula Hotels as No. 1.

This small luxury chain—with properties in just 10 cities—sets the standard for amenities tailor-made for road warriors: gyms and business centers are available 24/7 upon request, jet-lagged execs can indulge in a rejuvenating “sleep ceremony” at the spa, and some locations have no set check-in time. There’s also an obsessive focus on technology. In the Hong Kong, Tokyo, and Paris hotels, for example, guests control the TV, lighting, and thermostat, order room service, and send concierge requests by touching a bedside panel. (The Chicago and Beverly Hills locations are currently adding these capabilities.) And high-speed wi-fi is free—even in the Rolls-Royce Phantoms used for airport transfers in Hong Kong.

See below for the rankings of business hotel brands by survey category.
