After walking around plenty of neighborhoods in Seattle, I would come back to to Phil and Andrea's quiet cottage surrounded by lush foliage in the Mann/Madrona area every time I visit. If you're up for walking (which you should be, because Seattle is lovely to stroll) you can reach everything you need by foot, and it's relatively centrally located to anything further afield (including the airport). We are restaurant people and generally seek out food, so can't speak to kitchen functionality, but everything necessary seemed to be in place. The lofted bedroom is cozy, and washer/dryer in the bathroom is extremely convenient to have. Though it's attached to their home I think I heard some faint noises through the wall briefly 2 or 3 times over the course of over 3 days, and it has its own side entrance so feels very private.
