I mentioned this in a thread, but I think it deserves its own post. The Sherwood co-op, a 14 member student-owned co-op in the U District, has some openings coming up. Right now, there is a furnished room (sublet) open for Winter quarter, and a regular member room opening up Feb 1. Other than that, rooms open up fairly regularly, so we will also be looking for people for summer, next fall, etc.
House share runs about $600-$650 per month, which includes a bedroom, all utilities, DSL, NY Times, food, fully equipped kitchen, and a great community experience.
