Not what you might expect at the Westin
We stayed here for four days preceding an Alaskan Cruise. Location is central (1 block from monorail to the Space Needle). Restaurant food is very good - concierge very helpful (the woman from the Boston area was terrific - if you're from Mass. you'll recognize the hometown accent). Room was recently renovated and quite large. Bed was SUPER comfortable. Bathroom nicely appointed. Re: the room furniture - lovely, modern - NO drawers. The only drawers were 3 small ones in the closet. I personally don't like living out of a suitcase if I am staying for several days.
Re: the view. Of course they are showing the best views on their website - who wouldn't? The views will vary from nothing but buildings on the probably the first 15 floors to some obstructed views on 20-35 (there are 47 floors). The buildings are round so there are no lovely corner room views. The views from the hotel have not benefited from the construction of high rises one of which is directly in front of it. We stayed on 24 and had a view of the harbor which was decent and could look out to the right and see the Space Needle, but the view would have been spectacular without the recent addition of aforementioned building. I think the rooms in the north tower are probably better from a view perspective.
Re: the pool and spa area. I didn't go in the pool, but it is on the 4th (or 5th) floor and is quite nice with floor to ceiling windows. Not ditto on the gym which is bleak and has no windows, not nearly enough machines and of the machines it had, some were broken and some had pieces of the tv insert sticking out of them. Not a welcoming place to exercise.
Room service is insanely expensive. We were celebrating an anniversary and decided to order breakfast in. Service was quick and delivery professional and pleasant, however, $75 for pancakes, an egg white omelet, coffee, milk and juice seemed a bit over the top although the food was very good. Ditto re: $90 price for a salad and appetizer one night.
Parking - plan this one in advance - there are cheaper places nearby. About $35 + tax at the hotel for self park and about $41 + for valet at the hotel.
Laundry - if you are staying pre-cruise, wait until you get on the cruise ship for laundry service. Westin's is ridiculous - $3.50 for a t-shirt?
Finally - the dealbreaker for me - the billing. I've done a fair amount of travel in my day and have never seen a hotel add "estimated" charges onto a bill. Upon questioning they advised that they take the average estimated expenditure and put it on your card. Mind you, the hotel room was completely paid for months before we arrived and we were only paying for meals, etc. We ate breakfast at the hotel, I went to the desk and got the bill, noted breakfast was on it, saw the zero balance and left for our cruise. 
When I got home there was an email from Westin that said "final bill" and reflected the same zero balance. Imagine my surprise when I received another bill for $176.34. When I called I was told that the "final bill is not really final and if there were more charges I CAN"T EXPECT TO GET THEM FOR FREE". Really? Mind you we had spent and paid for more than $1500 at this hotel prior to that. I was annoyed and insulted by that comment. I believe that the term "final bill" should mean "final bill".
We would not stay at this hotel again.
