Very nice hotel
Overall, the hotel was very nice and my stay was pleasant. I was there for three nights on business. The location was nice, on the edge of downtown and a block away from a PeopleMover station. The two main restaurants (Roast and 24Grill) were nice, but Roast was much better and not much more pricey. If you go to Roast for happy hour, their bites and drinks were both insanely low priced and delicious - My colleague and I walked out with full and happy bellies for less than $50.00 including three glasses of wine. It gets REALLY busy so get to the bar early (4:30 or 5) for happy hour. 
Their (Westin) website is lacking so know there is a pool and hottub on site, the gym is nice and large and offers quite a bit for a hotel gym. The rooms are spacious, modern and nice - nothing terribly flashy but nice. 
The staff was nice, but not necessarily memorable - accomodating and polite which was enough for me. 
Overall, very nice experience.
