I have stayed at this hotel several times for business. The hotel has a lot going for it, starting with a wonderful staff. Everyone is friendly and professional, and they make you feel at home. Other positives are the location near the Space Needle, the size of the rooms, and the "easy upgrade" to a suite.
Where this hotel loses a star for me is the noise in the rooms. I like a humming hvac system, but in the summer the air conditioning is downright noisy. In addition, there is a lot of noise from other rooms or "in the walls" from plumbing and such. And (this could be easily remedied), there isn't a single towelbar in the bathroom (I've stayed in 5 different rooms and found this to be the case). Vanity size varies from tiny to normal...a tiny vanity with no place to hang a towel is very inconvenient.
Back to the positives....there is a nice selection of food for breakfast: cereal, fruit, muffins and bagels, yogurt, a waffle maker, and a rotating selection of meats, potatoes and eggs. Juice, milk, coffee, tea are all provided. There's plenty of room in the lobby to eat breakfast, or you can bring it back to your room.
There's a small exercise room, and no pool. As mentioned I've stayed here 5 times, so it has definitely worked for me.
