Not worth the hype...
I stayed here for a few nights on business in September. While the employees were very nice and helpful, I just didn't love this hotel, especially for business. The lobby provides a lot of seating and some private, which is nice for meetings but the restaurant/bar definitely get a bit "clubby" after 9 pm. We were here during a convention and it was extremely loud.
The rooms were nice- I was upgraded to a junior suite which had a small vanity area for makeup etc and a larger closet. Bed was comfortable but overall bathrooms need a rehaul- just seemed dated and cheap fixtures for a $500+ night hotel. 
I ordered room service for breakfast twice (once ordering oatmeal and once an omelette) and both were cold and just not tasty, especially for the price. I am sure there are better nearby options but there's no Starbucks or quick cafe type option in the hotel and I was pressed for time.
Overall, it was ok. I just wouldn't reccommend at that price, espeically when there are options like the Westin St. Francis with a better location, price, and vibe. However, it depends on what you're looking for. I wouldn't reccommend Clift for a family, romantic, or business trip but if you're in town to party, it could be a good bet!
