"Great location for the Arch and Busch Stadium. Their updated gym is appreciated and the staff are friendly and helpful. "

"This has been our third or fourth stay here. My family loves staying here when we see Monster Jam or if we have medical appointments. A few things that keeps us coming back back is the the staff. The front staff are amazing. There is a lady she has long braids and she is always there when I check in the evening and she is AMAZING everytime. I came in this time and she recognized who I was. The hotel could use some updates but who cares! The breakfast is amazing and they have WiFi which you don’t have to pay for! Thank you for another amazing stay and we will see you soon!! "

"A lot of history at Union Station that makes for a great atmosphere. And easy to relax due to the staff and how well maintained and clean everything is. "

"Thanks to the very nice young lady at the front desk the time of check-in - my stay was even more amazing! I informed her that I was there for Thanksgiving but to also celebrate my birthday. She said, oh well I have something to make it more special! When I got to my room, I had an amazing view of the Arch!! Thank you , thank you - for making my trip to the Lou even more special! "

"We stayed at 21C for an overnight getaway. The check in was seamless- the staff was very friendly. Our room was beautiful and clean (was missing body wash but it was quickly rectified). The robes were luxurious, a really nice touch. We enjoyed all of the amenities at the hotel; the pool, hot tub and sauna (all clean and enjoyable), the "nightcap at the museum" and the art museum as well. We had a reservation at the restaurant (best burger in town!) and went back to the bar for dessert and drinks later in the evening (I wish dessert was better). In the morning we went to the coffee shop for breakfast (so delicious!). Everything we needed was right there. The only negatives were; the pillows were not comfortable, the cups in the room for coffee were disposable and not mugs (I prefer mugs and that's what's shown on the website) and I wish parking wasn't so expensive. Overall, a really wonderful experience- we will definitely stay at the 21C again."

"This is an amazing place to stay! Multiple dining options within the casino was a plus. Once you get checked in you won’t have to leave again until you’re ready to check out and head back home."
