Nashville’s [1] most notable downtown hotel is 
Union Station (1001 Broadway, 615/726-1001, $160–270), a 125-room Wyndham Hotel located in what was once the city’s main train station. Distinctions include magnificent iron work and molding, and an impressive marble-floored great hall that greets guests. High ceilings and lofty interior balconies make this one of Nashville’s great old buildings, and hotel guests get to make it their home away from home.
Union Station is a fine hotel, with amenities like free turn-down service, a fitness center, wireless Internet, plasma televisions, complimentary morning newspapers, and room service. Rooms have cathedral ceilings, stylish furnishings, and a subtle art deco touch. The bathrooms have soaking tubs, walk-in showers, and expansive marble vanities. You can choose from a standard room with one double bed or a premium room with a king-sized bed or two double beds. Four suites are also available.
The all-suite Hilton Nashville Downtown (121 4th Ave. S., 615/620-1000, www.nashvillehilton.com [2], $170–240) is next door to the Country Music Hall of Fame [3], Broadway’s honky-tonks, and the home of the Nashville Symphony. It’s also across the street from the Nashville Convention Center. All of the hotel’s 330 suites have two distinct rooms—a living room with sofa, cable television, microwave oven, refrigerator, and coffeemaker, and a bedroom with one or two beds. The rooms are appointed with modern, stylish furniture and amenities. An indoor pool, workout room, valet parking, and two award-winning restaurants round out the hotel’s amenities. The Hilton’s combination of luxury and location make it one of the best choices for travelers to Nashville [1].
The Renaissance Hotel (611 Commerce St., 615/255-8400, $290–310) is connected to the Nashville Convention Center by a raised and covered walkway. Located one block north of Broadway, it stands 25 stories, providing impressive views of the city below. The Renaissance’s 646 rooms offer web TV, hairdryers and ironing boards, crisp linens, coffeemakers, and business services. For an additional $12 daily, guests can enjoy high-speed wired Internet access and unlimited local and U.S. long-distance calls. The fitness center is next door to an indoor heated swimming pool, whirlpool, and sauna.
