gross is an understatement.
I have been for business many times, I state in the top floor for diamond club. It was never the best place, not even close with the Double Tree standard. I was unable to enter my room, wait hours for them to open and repair. Another time was raining and I wake up when the water was pouring in. their answer "we do not have rooms to move you until tomorrow. next day lots of problems to be moved to another room. 
Rugs are dirty, smelly rooms. always something wrong. I will not recommend this one to my enemies. Many complains, no satisfaction...
