Overall, a good experience.
I stayed here for a convention in April of 2007 and was thoroughly impressed. I should mention that I don't do much traveling so I don't have much of a basis for comparison, but I do know good service when I see it. The staff was friendly and accommodating, and the one issue I had there was resolved promptly (I was under 21 at the time but wanted to use the minibar as a makeshift refrigerator- they comped me a fridge instead). The room was clean and well-kept, the bathroom was well-supplied and fairly spacious. I didn't bother with the restaurant or room service, just too expensive, and I wish parking wasn't so costly either. Nothing happened to really 'wow' me, but aside from the prices I really have no complaints; I will probably stay there again on my next trip to Seattle later this year.
