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
