Absolute 5 stars! They have given really thoughtful attention to detail in every aspect. I have stayed in Seattle many times, and this place is about the best experience I've had thus far. The in-law cottage had elegant touches, was very clean and well kept. The back yard space was relaxing and inviting, and quiet for unwinding at the end of the day. The location was ideal and parking was readily available. The process for checking-in was flawless. The price point made it an excellent value. They thought of everything!
This place is perfect for a couple, or for one person traveling for work which was my situation. I would highly recommend.
