I recommend this site. It was very clean and well-equipped. It is small quarters but it is well-designed and spare in a kind of European way. Clearly a lot of thought went into the design. There is a small kitchenette in the room in case you want to just warm something up or make a coffee, and there is also a spacious and well-equipped shared kitchen where you can do more significant cooking if you choose. We cooked several meals there, which helped with our vacation budget. We had the bad luck to stay here during a heat wave and it was very hot (there is no a/c) but the host quickly provided us with fans to help blow out the hot air. BTW, It isn't unusual in Seattle for places to have no a/c-- many of the restaurants didn't have a/c either (in fact some of them literally closed down because it was too hot for the workers!). Ballard area is a good location -excellent farmer's market as well as access to many excellent restaurants.
