Top Waterloo Hotel Reviews

Hampton Inn St. Louis-Downtown (At the Gateway Arch)

8/10 Good

"The hotel was clean, though it was beginning to show some signs of wear and tear in a few areas. The hospitality was outstanding and exactly what I’d expect in the South, with the staff going above and beyond to make us feel welcome and well taken care of. The staff in charge of breakfast we hands down the best and it made it a great start to our days!"
