Great location!
I was recently in Seattle for business, and I stayed at this hotel for a month. I've stayed here several times, and it's become my choice of the Starwood hotels in the area: it has more comfortable beds than the W, and it blows the Seattle Westin out of the water (a dump, by comparison). The gym is great, the hotel bar and separate restaurant are nice, and the lobby is beautiful. The valet guys were very nice, and fast. Internet access is a little flaky, and the housekeepers can be a little inconsistent from day to day - but nothing major.
