Top Waterloo Hotel Reviews

Marriott St. Louis Grand

2/10 Terrible

"Disgraceful in that the hotel would not credit for 1 night due to family emergency."

Hyatt Regency St. Louis at The Arch

8/10 Good

"Booking through Expedia was a bad idea. I didn't get the 2 queen beds I thought I was getting, I didn't get the free breakfasts the booking said I'd get, and the site said I'd have a choice between paying 40.00 for self parking and 50.00 for valet parking, upon getting there at 4p.m. I was told by the hotel staff that all the 40.00 self parking spots were taken so I was forced into paying 50.00 for the valet service. I'm not happy."

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

10/10 Excellent

"Wonderful hotel! Will definitely stay here again. Within walking distance to Busch Stadium, ample parking (oversized vehicle), and great breakfast! The staff were incredibly friendly and helpful! Everything is secured/locked down, and controlled by key cards (ie. No one can walk right in off the street). Great place for kids, with plenty to keep them entertained!"
