I am often up in Seattle visiting the mothership. I usually stay in Seattle and just make sure I time my commute to avoid the craziness across the SR-520 floating bridge and when I do I always stay at the W. If you are looking to minimise the commute then your only choice is Bellevue and out of the two properties I would only stay at the Westin. The Sheraton there is only a notch or two above a Four Points and whilst cheap, is in dire need of a refresh.
