Really Great Location
I stayed at this Hilton for a conference. Loved the convenient downtown location. Very close to great restaurants, the Epicenter, and some NASCAR thing. 
We had amazing service at the meals and parties staffed by the hotel. The catering employees could not be more attentive. Especially loved Lisa, Maria and Clotilde. 
The room had an enormous flat screen, comfortable mattress, linens and pillows, great decor, and was immaculately clean bathroom.
I especially loved the glass-enclosed marble shower. So luxurious. 
Our room was near the elevator, but I never noticed any noise. 
Would have liked more vending machines for soda. Also, when we checked in, we requested more towels, but never received them. (The maid helped us out the next morning.)
Really can't say enough about the staff. From the valet to the desk clerks to the concierge, every one was top notch.
Special thanks to the concierge for directing us to Kings Kitchen for dinner. Really enjoyed it. 
I hope our conference returns to this venue next year.
