The Loews Vanderbilt is a great business hotel. While it is not (like Union Station in Nashville or the Palace in San Francisco) a unique hotel experience, it is always dependably excellent. As previous reviewers have noted, the staff at this hotel provide the kind of service to which a Ritz aspires. Superb, superb, superb. We have stayed at hotels around the world, and the Loews Vanderbilt has, on average, the best staff we have ever encountered.
The room decor is predictably nice -- nothing exceptional. The primary structural problem is the lack of sound-dampening quality, and if you end up with some "rowdies" on your floor, you will hear it. However, if you use an AmEx for your reservation, you will be upgraded to the Club Floors (very quiet) which provides a nice two-story English club-type lounge for your use during the day. One does feel a bit gouged on parking, but the other hotels of this caliber in Nashville also have parking fees. Interestingly, go down a single star rating and no one in the same geographic area charges for parking.
I don't know that in all the times I have stayed in this hotel I have seen anyone with children (dogs frequently, but children, never). Perhaps it is the absence of a pool, but this is really a business-oriented hotel. The hotel's proximity to Vanderbilt and Peabody is unmatched, and provide a beautiful park-like walking environment in the morning and evening. The hotel is also within (barely) walking distance of Centenial Park, which is also very nice. Numerous restaurants around the hotel, running the gamut from Jack-in-the-Box to Ruth's Chris. Proximity to Hillsboro Village provides access to great ethnic food (good Indian restaurant immediately adjacent to hotel).
Having stayed at virtually every four star hotel in or proximate to downtown Nashville during the past year (about once a month), this is the hotel to which I consistently return.
