Wow - This place blows. Save yourself.
I stay in downtown Seattle every week. Mostly at the Grand Hyatt and the Hyatt at Olive 8. Trust me. Those properties are WAY better. This place is horrible. tiny rooms, I get a fantastic view of the parking garage so when cars have their headlights on you get wonderful night lights. (They offered a free movie to cover it, but I mean. who watches movies when on business travel)
So here's the thing. I'm not familiar with SPG, but apparently there is this green program where they don't clean your rooms or give you new shampoo. Anyways - I declined it on check-in. But for whatever reason, they kept it on. When you work late on business travel, the last thing you want to do is to come back to a room that has no new towels, shampoo or just basic house keeping. Am I a little messy? yes. but..that's the point of staying in a hotel for business travel. You can focus on why you are in the city in the first place. 
When I went to complain, I got about lukewarm support and even challenges to my complaints. 
Just do yourself a favor, don't stay here for work. The W's are cool and chic...but not very helpful for a good nights rest.
