Stayed at Daniel and Fumiko's place for one night on a long layover. The location was in a good neighbourhood with excellent access to the airport train. Clean basement room in a very quiet house, with solid amenities and really easy check-in and check-out. Having a self-serve breakfast included was really appreciated, as well. (Ironic that so few Airbnbs actually include breakfast!)
Just a couple of issues: communication wasn't ideal, with some really chilly responses from the hosts through the app, for some reason. When I mentioned some issues I was having with the wifi they weren't super helpful. Never heard back when I told them I had checked out, either. Other than that, it was still a great place to stay during my short visit to Seattle.
