This was one of the nicest Westin's that I have stayed in. I was traveling with a large group of people (a work outing), and check in was very fast and easy. They had bottles of water, cookies and fruit for us upon arrival. My room was very large, one queen size bed(with lots of pillows and very comfortable) a couch, coffee table, desk. It was almost too large for just one person. The room was very nicely decorated with graffiti type wall art, and very modern light fixtures. The bathroom was very large as well, and had a separate bathtub and shower.
While on the subject of the shower, it was one of those rain showers, and had such great water pressure that I didn't want to get out!
The staff was extremely helpful and went above and beyond. We asked the desk staff for recommendations to get a drink before the Cardinals game, and they told us aobut a place called The Flying Saucer, which was just up the street, and was a great place. As we were leaving the hotel it was raining pretty hard and they offered us umbrellas, but we declined as we didn't want to carry them around all night. They also suggested that we walk through the hotel to stay out of the rain, and instead of just telling us how to get there, he actually walked us all over and through the hotel. It was very unexpected.
We went into the hotel bar for a bit, but it was very crowded and there was only one bartender working, so we didn't stay long and ended up not even getting any drinks. It was right before a Cardinals-Cubs (big rivalry) game, so that was the reason for the crowd I am sure.
We went to the game, and there was a long rain delay, so it was nice that the hotel was literally right across the street from Busch Stadium, so that was very convenient.
If there was any negative, it was my view. Most of my collegues got views of the Arch or the baseball stadium, I had a view of the parking lot. When making reservations, make sure you suggest a room with a view.
I would highly recommend this hotel and would stay there if I ever find myself in St Louis again.
