Downtown St. Louis has an impressive number of hotel chains ensconced in renovated historic buildings. In addition to the choices below, consider the Westin St. Louis, located next to Busch Stadium at 811 Spruce St. (tel. 314/621-2000; www.westin.com/stlouis), which gave new life to a group of former 19th-century railroad warehouses with a gorgeous, smoke-free contemporary interior; and the upscale Hilton St. Louis Downtown, 400 Olive St. (tel. 314/436-0002; www.stlouisdowntown.hilton.com), in the historic Merchants-Laclede building with many of its original features intact (a former vault is now a gift shop). Sheraton St. Louis City Center Hotel & Suites, within walking distance of Union Station and Busch Stadium at 400 S. 14th St. (tel. 314/231-5007; www.sheraton.com/stlouis), occupies four floors of the renovated Edison Brothers warehouse, distinctive for a trompe l'oeil mural that draws its imagery from St. Louis landmarks and the 1904 World's Fair.
