The elevator was very loud. The front desk offered ear plugs at check in but I was traveling with a 14-month old. This is unsatisfactory and should be properly addressed such as updating the equipment. Needless to say it was not a restful night of sleep before an early flight. Will not return.

Room was nice. Bathroom was great in the suite we had. I think the best part was the breakfast. Made to order omelets and waffles. We stayed here to see Zack Bryan in concert. It was a drive to the Americas Dome but we liked this hotel. We will be staying here anytime we come to St. Louis.
