Top O'Fallon Hotel Reviews

Drury Plaza Hotel St. Louis at the Arch

10/10 Excellent

"Great stay! My husband and I were in town for the Usher and Chris Brown concert. The evening dinner was great! Breakfast was great every morning. Rooms were clean! Staff was remarkable. I would stay again!"

Pear Tree Inn St. Louis Near Union Station

8/10 Good

"We had a good sleep in this hotel for 6 nights. That is the most important thing. The beds and linens were clean and didn't smell like toxic chemicals. The bathroom ceiling had been poorly repaired, and wasn't finished all the way. There was black stuff on the ceiling, a pretty big amount, that looked like black mold, but they were booked so we couldn't get a new room. Our A/C also broke for almost two whole days, but the maintenance guys were very quick to come fix it. They had to come three times, but finally got it repaired on the third try. It wasn't the end of the world. We were comfortable. I probably wouldn't book that hotel again, but it was good enough, and the staff were great!"

Drury Inn & Suites St. Louis O'Fallon, IL

10/10 Excellent

"Pool was so much fun and my daughter’s birthday was recognized by the staff when we checked in that was so nice! Also I thought I left something in the room the staff went above and beyond to look for our missing item. We also enjoyed the drinks in the evening."
