Stayed here while working the NASCAR race at the nearby Charlotte Motor Speedway. I'm glad the room was paid for by the company, as I don't feel like it was really a $170/night room. There wasn't anything wrong, particularly, but it wasn't "all that" either. The gym and pool looked decent. The bed was very, very comfy. Food (including room service) was WAY over-priced.
The location right downtown, near the convention center is great. I would suggest taking a walk over to Brevard Court, near Church street to hit the little alley of bars and restaurants. They've got great atmosphere and reasonable prices (The Belfast and Valhalla in particular).
