The Sheraton Gunter Hotel 's roots date back to the first year of the Republic of Texas and assure the Gunter a prominent place in Texas history. The hotel sits on the corner in the vital part of San Antonio 's business center. In 1912, the National Association of Advertising Men gathered at the Gunter Hotel. Immediately they coined the phrase, "The Gunter Hotel, at the Center of Everything." Today with the remarkable growth and changes taking place along Houston Street, this 89-year slogan is still accurate!
