The best business hotel in the world is the Palacio Duhau-Park Hyatt in the Argentine capital Buenos Aires, with rooms starting from 300 euros a night.

Readers of travel magazine Travel and Leisure ranked hotels on a list of services and amenities to come up with their 20 top business hotels. Nine hotels in Asia, nine in the United States as well as another hotel in Buenos Aires were on the Top 20 list, which doesn't include a single hotel in Europe.

Many of the winning hotels offered free Internet access and a 24-hour conference centre, some had rooftop pools and extra fitness facilities, while one had an award-winning Gordon Ramsay restaurant.
