This hotel was fantastic! Check in was easy with friendly staff, the room was beautiful and well appointed. Breakfast was advertised as a Continental, however they had hot options as well, which was great. Every staff member we saw in the hotel said hi and was friendly. I would definitely stay here again!

It was a fine location if you need an overnight stay before the airport. Quick and efficient to the St. Louis airport, but not any restaurants around. Need to eat at the hotel restaurant.
