"The room was clean and the breakfast was good as well…."

"Staff could not have been more pleasant or helpful. The breakfast was exceptional, and the lady that took our order\served us was wonderful. The coffee maker in the room is my only real complaint It did not work well and made really bad coffee. No coffee available in the lobby."

"From Ty and Jimire at Valet, to Marquis for check-in at the front desk, Jay at Good Press, Drummond for check-out, and to all team members we spoke to, I was enamored at the level of involvement and genuine concern for my happiness with our stay. We came into STL for a concert at Enterprise last night and only stayed the one evening. Thankfully, we made time to embrace almost all amenities offered by 21C. Work stations were plentiful and peaceful. My morning started with a quick dip in the stunning pool. Glad they kept so much of the original work as part of the Historic Building qualifications. Just beautiful. Everything related to those amenities were stellar. The moon rain experience, sauna, and gym were all on point. Exactly what I needed! Good Press was awesome. Had the smoked salmon and a chai tea latte. Perfect a setup for breakfast and reasonably priced. Ate while I worked in the not so busy lobby and got tons done. Didn't eat at Idol Wolf, but did get out back to the sitting area behind the hotel. All spaces were clean, thoughtfully put together, and extremely well designed. The exhibits all over brought a different, special touch to the hotel. The 24 hr accesible museum was unreal and from my understanding, switched up every so often. HAPPY to be present for Future is Female with my MIL and BFF, especially when our trip was centered around Mother's Day. I would easily return to this location if ever in STL again. HIGHLY recommemd."

"Pefect"

"Room was clean, earning 2 stars. However, this location is right next to a kid's theme park so the indoor pool is a huge selling feature for families. A lot of kids all over the place. Hot tub was broken. They said it just happened, but it's in other reviews and they were downright rude about it. Food provided at the happy hour is hotdogs, chips and cheese... kid themed food. Would not stay here again. Parking is $19."

"The staff was really great, but I just kept having one challenge after another. First, I was put in a room right next to the music venue, and the sound was pounding! I was then moved to a much better room. I ordered room service via the online system, but they never got the order. Two hours later, they did comp the meal, but needless to say, I had been waiting a long time! Not sure that I would stay there again."

"Lo recomiendo muy buena atención"

"Amazing views but the evening staff was not welcoming "

"Rundown property but great location. Staff was good. Breakfast - meh - better fresh fruit selection would have been nice. Bathroom was two feet from bed and it had no fan."
