Nice room, reasonably clean. Some hairs in the tub though. Room was hot on arrival, the AC isn't very strong. Check in was fast, no line.
But the reason for one star was when another guest tried to get into my room at night. I could hear that he was trying his key, and he couldn't get in (obviously, this was my room). But he came back a few minutes later with security guard, who actually let him into my room, without checking his ID and seeing if he actually was allowed into my room! What a terrible security lapse! A guest should never be able to convince a security guard to let them into someone else's room!
Because of the security problems, I am ranking this only one star. Guest security is a basic skill that any hotel has to master. If travels take me to Charlotte again, I won't stay here again.
