Motel 6 Hazelwood, MO

10/10 Excellent

"Inexpensive, friendly staff, and clean!!! When a room is under $100 a night I don’t expect fancy amenities. My only expectations is that it’s clean and the staff is kind and helpful. Which is the bare minimum any hotel should provide. This hotel checks all the positive boxes! Plus, the room had a mini fridge & microwave, both clean. And there is an outside pool, which of course is seasonal."
