Location, location, location. And some nice perks too.
As others will attest, this is a great location if you're into sightseeing, window shopping and a variety of dining options.
I was a little hesitant about my stay here - the reviews all seemed so mixed! It's a transitional area - trendy, accessible, with a few street folk milling about - nothing that made me feel nervous or unsafe though. 
The temperature in Seattle was perfect during my stay, so the open windows and fan provided just the right amount of airflow. I was on the side facing the courtyard so street noise wasn't a problem for me, though the walls were a little thin. 
The coffee, sodas, water and popcorn were a nice complimentary touch and I could see how the kitchenette would definitely be useful to many travelers. 
The staff was super nice and helpful - no complaints there. And again, the location can't be beat. My room was clean and I had a great stay - and since that's pretty much all I look for in a hotel, I was a happy camper.
