"Loved our room! The shower was awesome and the hot tube was very relaxing. The room had two large smart TVs. The bed and pillows were very comfy! The pool was clean with nice seating. The breakfast was great. This Place has the charm and feel of an older hotel but with modern conveniences. Will definitely be a repeat customer. We highly recommend if you want a peaceful place to stay while having a great time."

8/10 Good
"Room was clean, bedding was clean, there were no signs of pests which is extremely important for us, the staff was polite, and helpful. The only complaint we have is we were put in a room next to the rear entry which when other guests were arriving and leaving the entry door was slamming all hours of the evening/ night. Next time we stay at the hotel in St. Claire, MO we will ask for a room away from the rear entry door. Simple fix. It was a nice room for the price. All bath towels and wash cloths were clean and available..bed smelled clean. The complimentary coffee was descent. Everything was there as was needed to be comfortable in a hotel."
