10/10 Excellent

"The pool and hot tub 👍"

Quality Inn Near Six Flags St. Louis

8/10 Good

"The room was large and clean. King bed was comfortable. The staff that checked us in after 10pm were very helpful and friendly as were the morning staff. Shower was decent with adjustable shower head and decent pressure. Location seemed safe, although we weren't here very long. The breakfast, however, was one of the worst we have had on an almost 3 week road trip. We don't expect anything super from free breakfasts in hotels but this was not up to par. They had brown bananas, dry biscuits and sausage gravy, make your own waffles ( these were pretty good) with generic syrup, two types of cereal and some yogurt ( not Greek with protein). So nothing healthy to choose from at all and really no protein. I would have been happy with some oatmeal and toppings....or even jelly to put on a dry biscuit. Most all other free breakfasts offer oatmeal, eggs ( some are powdered some not), jelly choices, toast, apples and bananas. So I would stay here again just because of the nicer room and very friendly staff but don't figure the breakfast in on the price."

"We had a wonderful stay! The staff was friendly and welcoming, and they made check-in and check-out quick and easy. Our room was spotless, the beds were comfortable, and everything we needed was provided. The location was convenient and made it easy to explore the surrounding area. Overall, we had a relaxing and enjoyable experience, and we wouldn't hesitate to stay here again. We highly recommend to anyone visiting the area!"
