10/10 Excellent

"Very good accommodations"

Heritage Inn & Suites St. Louis/Fenton, Trademark by Wyndham

2/10 Terrible

"Room didn’t have handsoap or anything. Asked for it and they said they’d bring it and never did the 4nights we stayed. Room was only somewhat cleaned one time and that time they took all the towels and only left one to shower. Had to call and ask for more towels and had to use wash rags to dry. AC had a rattle at all times that no-one cared to address it. Won’t stay with them again…"
