The JW Marriott Buckhead is an upscale high-rise hotel that is literally attached to the Lenox Mall.

The Atlanta Marriott Buckhead Hotel and Conference Centre is a standard older concrete mid-rise property across the street and a large parking lot from the Mall. It was formerly a Sheraton, and with that comes the small cookie cutter rooms, poor sound insulation, etc. As for the "recent renovation", I believe that only references when they renovated to change it from a Sheraton to a Marriott a couple of years ago, so it is just your standard Marriott room (not even the newest generation of decor).
