The house my wife and I are leaving on Vashon Island (a 20 minute ferry ride from Seattle) is available for a 3 month lease starting at the end of February. It’s a pretty great place just up the hill from a beautiful Puget Sound beach and lighthouse. Here’s the ad: http://seattle.craigslist.org/see/apa/4850406461.html
Here are better photos with our actual furniture in it: https://m.flickr.com/#/photos/teamgenser/sets/72157650335823075/
We are happy to arrange to leave some furniture for a short term renter, too.
