A Wonderful Westin...A Great Business Hotel
We were at this hotel for a national conference. It's big and busy...check-in took about 15 minutes. It has the wonderful Westin Heavenly bed and shower. This hotel is next to the Charlotte Convention Center...great location if you are attending a meeting here; however, for the majority of the downtown restaurants you need a taxi or have good walking shoes on. Everyone was friendly and the valet service is very quick and prompt. You do not have to call the valet in advance...your car appears in minutes. 
Don't bother with Embers...see my review of this awful restaurant. There is a Starbucks in the lobby. 
Private cars are always waiting at this hotel, and they are almost equal in cost to the taxi.
The new Ritz Carlton has a much better location when it comes to restaurants in the area, but this hotel is great if you are aware of its location.
