Like more of the average starred hotels I took with a grain of salt when walking in, it had a modern but pleasing look. Checking in was a little confusing but staff was very helpful. Then when getting in the room it was tad bit smaller than expected, Although beds were comfortable and didnt mind the a/c noise as long as it worked. Plenty of towels were provided I would say I would comeback if I were planning to go to St.louis again

Narsty dark stain on the mattress about 2.5 feet long. Moved rooms. Heard the people above us throughout the night just walking. The hotel seems to have very thin floors. Received a noise complaint at 8:30am when my family of 5 were trying to gather things to leave. The pool was clean. Parking costs 30 a night.
