Nice hotel, GREAT location!
My wife and recently stayed at the Omni Hotel. The hotel is located right in the heart of Downtown Charlotte, which we loved. The room was very nice and big. The bed was very comfortable. Also, we found the concierge to be very helpful. There is a Walgreens and several restaurants (including Starbucks) on the plaza level. Overall, we really enjoyed our stay. 
There were only a couple of things that we didn’t like. First, while the room is large, the space is not used well. The bathroom ridiculously small…to the point that was hard to get out of the way of the bathroom door when closing it. The sad thing is that there is unused space that could be used to expand the bathroom. Second, though the room clean, there were certain things (the curtains and the counter) that we could tell hadn’t been cleaned in a while. Despite these two shortcomings, we liked the hotel and would stay there again.
