The Marriott St. Louis West is a full-service hotel known for its friendly and professional staff, who provide good and exceptional service. The property is described as an old Marriott that is due for a refresh and needs some updating, with notes that the building is old, hallways can appear stained and musty, and some areas like the M-Club can be filthy and dirty. The TVs are mentioned as needing replacement. However, the hotel also earns praise for feeling like home. Rooms are generally found to be spacious, fairly clean, good enough, and spotless, with quiet A/C, though some note thin walls and occasional issues like low shower water pressure. It is considered a halfway decent place for a clean room and basic amenities. The hotel's bar and restaurant are good, and the food receives high marks for being exquisite and delicious, with a culinary team that accommodates allergies. The venue is also highlighted for successfully hosting events like weddings, with flawless execution, beautiful decorations, and a team that is supportive, professional, and attentive to detail.
