Just stayed last weekend
I actually had a very good experience there. Had a corner floor high floor with a nice view. Room was spacious (it's a "deluxe" room, which is a bit larger than their standard rooms), and furniture/decor was standard Westin. Large marble bathroom, with separate bathtub and shower (the two shower head variety). Fridge in room, which was great. High speed internet for CAD$10 a day. Parking no longer free, but at around CAD $9 a day still not bad. Had a great dinner at the Le Continental restaurant. Very pleased with the service and the food.
Overall, we were very very happy with our stay there, and would definitely go back. While this is not the best Westin there is, I've seen much worse.
