Magic doesn't joke when he sais this eco-building isn't completly sound proof and that the people staying in it have to respect the "quiet time" (between the evening and the morning) : just dragging things on the floor, or heavy footstep seems like loud noises for the neighbors. We didn't realized that until we've heard the people upstairs doing so, and maybe we also were too loud the first night.
But there is no need to stay in the building that much because there is a lot of very good places to go for lunch & dinner nearby : the building is just in the proximity of several college universities, which attrack a lot a activities suited for students, including affordable and nice restaurants, coffeebar, bar, etc...
Globally I recommand this place to stay in Seattle if you want a good quality/price ratio (it may seem a little far - and high - from the touristic places in town, but as we've learn during the stay, buses and streetcars are very effective).
