Everything is good
Starting with the check-in, everything is smooth and easy. While it's a busy, noisy place because it adjoins the convention center, I didn't find that there was any noise or disturbance on my floor or near my room. The room is neat, clean, and well kept. Service was good.
My only complaint, if it is that, is that the gift shop is part of the convention center, not the hotel. This means that you can't charge things in the gift shop to your room. A minor inconvenience. On the other hand, having it connected to the convention center and other hotels and office buildings is extremely convenient, especially in bad weather.
