Top Arnold Hotel Reviews

Hyatt Regency St. Louis at The Arch

Hyatt Regency St. Louis at The Arch

10/10 Excellent
"We loved the clean, comfortable room and friendly staff. At check in, the front desk provides an area map to the guests, which is very helpful. The location is great...walking distance to several sites, including Busch Stadium. Our only complaint was the poor water pressure in the shower, which really is not a deal breaker. We had a short stay and did not get to experience all the amenities, but we will definitely be back!"

Heritage Inn & Suites St. Louis/Fenton, Trademark by Wyndham

8/10 Good
"I have stayed at this hotel a few times. The value is good - a better than expected hotel for the price. There were 2 issues for this last stay. I had a room with an adjacent wall to the elevator area, and the elevator is very loud and clunky when the door opens and shuts. I could hear it all day and all night long (good thing I had good earplugs). Make sure to get a room away from the elevator. Also, the cable tv system is a mess. The channels don't match what the cable guide on the TV says nor what the icon in the corner of the screen says. Also, many of the channels they're supposed to have say "no signal." Not a huge deal but definitely annoying. A simple piece of paper in the room which lists the real channels would certainly help."
