Sheraton Seattle a Great Downtown Choice
We spent three nights in October at this Sheraton. We used Starpoints (10 K per night) fore the stay. Online rates for standard rooms were about $169/night. Check-in was speedy and efficient. We were on the 29th floor, the Starwood Preferred Guest floor with a north facing view. Speedier elevators were available for those on floors 20 and above. The view of Puget Sound was obtained by looking obliquely to the west and a sliver of the Space Needle was apparent between two building to the north. We had a room with two double beds. We had no problems with the room and our son and his family were able to get a close-by room when they arrived a day after us.
The Sheraton has a nice pool on the top floor which our grandkids enjoyed. SPG members can get a $10 drink credit, 250 Starpoints, or free in-room wifi as a gift when staying. Go for the wifi which can allow up to 4 devices per room.
The hotel is near most downtown attractions: Pike Street Market, Monorail to Seattle Center, and a few indoort shopping malls.
If you drive, expect to pay $44 per night for valet-only parking. A self-park lot is a block away for $30 per night. 
We did not eat at the hotel given the plethora of restaurants nearby.
