We would have loved t to stay much longer if there had had been more days available as it is such a lovely place; right by Lake Sammamish with own jetty and a boat to make the most of the lake (life jackets provided as well) and even though the cottage itself was tiny it was well propositioned (bedroom might be too small for tall people) with a veranda upstairs to enjoy gorgeous scenery and a shady deck downstairs. It is quiet apart from jet skiers.
You will need a car to go shops for grocery, however, there is a small 7-11 nearby and owners have left some items like oil, sugar, etc.in the cupboard for your use.
My teenager son was very content with an excellent wifi.
I would go back anytime.
