It must be the location, everything else was average (at best)
I booked this hotel by accident. See below.*
It was okay. There's plenty of parking on 3rd Street, in front of the Roman church. So skip the $15 gated/guarded parking if you tend toward risk seeking. It worked for me.
At all times there are three to four staff in the lobby, one of whom attends to the slow moving queue of guests. I have no idea what the others do, except that one of them assured me someone would be with me soon.
Our original allotment of bath cottons included two towels, one hand towel and zero wash cloths. A message at the front desk had a new supply waiting for us when we returned later that night
The hallways were dingy, with a gaping hole in the wall leaking plaster dust, barely obscured by a jerry-built cardboard veneer. Nasty
Typical fire doors were not merely loud, but it's hard to escape that federally mandated nuisance. 
In short, you will stay at this hotel if you're seeking touristy Beale Street debauchery and want a stumbling-distance crash pad, or if your convention is downtown.
Otherwise, avoid it.
*I booked through Travelocity, which listed only two 4-star hotels among their "Secret" options. One was The Peabody, the other was the River Inn. I'd have been willing to pay a hundred bucks plus tax for either.
One bait & switch later, I was stuck with the Crowne Plaza, which Travelocity ITSELF lists as a 3-star.
Travelocity's man in Mumbai -- who probably gave his name as "Dan" -- could barely understand my complaint. So I paid $116 for a serviceable hotel. Lesson: Do not trust Travelocity.
