Sonesta International Hotels got its start when real estate mogul A.M. “Sonny” Sonnabend convinced 6 other investors to purchase the Preston Beach Hotel in Massachusetts. By 1944, the company owned 5 hotels, including the Biltmore and the Palm Beach Country Club in Florida.
Today, this international hotel chain has 200 locations in 8 countries, with the company adding 81 extended-stay hotels and 22 full-service hotels and resorts in the US, Canada, and Puerto Rico in August 2020.
The company opened 65 new hotels and resorts in 2019 alone.
In July 2022, Equinox Hospitality acquired four properties in Texas from Sonesta International Hotels. Equinox Hotel Management, a subsidiary of Equinox Hospitality, will operate the properties.
Sonesta International Hotels maintains a corporate office in Newton, Massachusetts.
