After a needed refresh was completed a while back, it's been a better experience. It has a larger bar and restaurant area (compared to similar hotels), and a pretty nice courtyard and outdoor pool. The rooms are pretty standard for this class of hotel. There is also a good sized workout area and another pool at that level. Quick access to the airport and rental car agencies.
Excellent inside, a little dated outside. I enjoyed my brief visit to the St. Louis Airport Marriott. The restaurant is good and the interior well appointed. I was meeting a friend and we enjoyed the fried ravioli a I enjoyed the hamburger entree. The wait staff was excellent The outside of the Marriott could use some updating - it definitely looks like it popped in from the 60s - but it is well kept and the inside well updated.
It was a nice stay, the staff are very professional and the breakfast was great. Liked the mid century mod vibe of the hotel. The room was clean however the floor in the entrance of the room was wet but they had fans in the hall trying to dry it. At night we came back and there was someone (not staff) smoking crack in the back lot. But other than that I'd come back.
