Bad room, then upgrade
I am a Starwood Preferred Guest & always choose a Westin if there is one in the area. I am extremely loyal to the hotel chain.
We stayed here August 2012 - got a great rate on expedia. Upon check in, we were told there is not a room available, however we "lucked out" and could get a "good room". When we got to the room, we realized we got "scammed". We were squished in the tiniest corner room I've ever laid eyes on. It was so small - the toilet & vanity were not even in the same room - the vanity with mirror was outside the bathroom so when I got up before my husband to get ready, I woke him by turning on the lights & hair dryer - there was no door. The only door was to the shower/toilet. We were also woken up countless times by street noise. (The room was on the 7th floor) It was literally the worst room ever. 
The reason I gave this rating "average" vs poor was because the manager of the hotel redeemed it for us. When I called that morning at 8am to complain - he found us another room, and put us on a concierge night for our 2nd night there which was a normal sized room, normal sized bathroom and high enough on the floors that we were not awaken by street noise.
If given the choice - I would not stay here again which is sad because the location is excellent. You should also know that the only parking option is valet & it's $40 per day - which is really expensive.
