DIRTY ROOM, POOR SERVICE AT THE FRONT DESK, GOOD CONCIERGE THOUGH
We stayed here for 3 nights enroute to other locations. We have been Marriott Award members since the program began. Our experience at this hotel was one of the worst we have had in our travels. At check in, our reservation for a king size bed was denied. They put us in the basement area with two double beds saying there were no other rooms. The room they gave us was dirty with numerous rug stains (see pictures). The curtain did not block the entire window so light would not have been blocked in the morning. Apart from its condition, the room was small, particularly the bathroom. I complained at the front desk upon seeing the room. The front desk clerk insisted there were no other rooms available. I asked for the manager. I showed him the digital pics I had just taken of the room and this finally persuaded him to look on the screen. Immediately, another room was available. The clerk had not been honest with us. 
We stay at lots of Marriotts and we have noticed that the quality of the Marriotts we have stayed in has deteriotated. Four of the last five have been unsatisfactory. Once dependably reliable, the chain seems to us to have lost its commitment to its customers for a good, clean room.
There were two bright spots. The lady at the Concierge desk was very helpful and efficient.
Secondly, the waitresses in the main restaurant were quite helpful and friendly.
