This was one of our best experiences on Airbnb - a peaceful, well-appointed place for restful sleep, great walks, and relaxing with family.
We stayed over the Christmas holiday, and our preparations were quite smooth given how well appointed the kitchen was. The washer/dryer were so quiet and efficient we wanted to take them home with us, and the living space was very comfortable. We slept well on bed, and our son said the extendable day bed in the living room was great - he slept on it un-extended.
As for environment, this is a downstairs room with people living overhead. The noise level from our host living overhead was quite reasonable - it didn't bother us in the least, and evenings were very quiet. Situated by Green Lake, we took a lot of walks around the Lake, and up to the restaurants around TangleTown and the town center area - so many great little restaurants, pubs, groceries and coffee shops in the area.
We will definitely be back when we visit the Seattle area.
