Kristin is a really good host during my 4-day stay. If you follow some basic rules she wants you to, there won't be any trouble during your stay. And they are really basic.
The drain, as Rudy mentioned below, works very slow. Also during my stay, since the room door had no lock, I couldn't keep my stuff safe.
Other than them, everything was great. The neighborhood, Lake Washington, fresh air, and etc were fantastic.
