Great Location
Our recent four night stay was very good. We took a 5th floor room after being told that there was no desk in an available 11th floor room. Our room was on the small side for two people. We had to make sure that the TV/wardrobe doors were closed at night to avoid running into them if we got up in the night. 
We also had issues two nights getting cabs for dinner. The bellman kept calling with no response. We were told that it could be 20 minutes to a 1/2 hour for a cab to arrive due to traffic and a baseball game. We ended up walking the first time, and the second time were directed to a taxi stand two blocks away where we got a cab right away.
We mentioned our problem at the front desk and were pleased to recieve complimentary breakfast vouchers for two days.
The location is great, as others have mentioned. Its about 4 blocks from the Pike Market, and the Monorail to the Space Needle leaves from next door. The light rail station from SeaTac airport is next door as well and is only $2.75.
