The problem with converting old factories & warehouses into hotels is that you'll have to compromise on something.
In the case of the Westin STL, the compromise comes with the design of the place....it's a maze!
If you're trying to get to the gym or staying in the adjoining part of the hotel, getting around is a bit of a mind bender.
After having been moved to a bigger room- as my first one smelled of a chemical floor cleaner (and a stunning vis a vis onto a wall), I had a pretty decent view and was quite content.
The usual amenities in the bathroom were nice (though sparse when compared to the Four Points I was coming from in NYC SoHo).
Internet connectivity didn't work very well (a question of access point density that's all) AND though the policy that the 11bucks a day was PER DEVICE was waived at checkout (iPhone, work pc and personal PC for 33 bucks a day?)- that policy needs to be reconsidered imho.
The gym was being renovated- though when completed I am sure it will be very nice.
Overall, the service was detail oriented and the team clearly focused on keeping the customer satisfied- which I can only salute.
