I had a lengthy stay with Tom and Corinne along with 2 other friends. It was absolutely brilliant. They are very friendly and welcoming and helpful in all manner of ways from assisting with bags to telling about the local area and what was on at the time.
The unit is very comfortable with large airy rooms. No kitchen as such but we had microwave, fridge, toaster, kettle and coffee pot. Laundry facilites are available The TV is basic, no cable but netflix is available as well as wireless internet. There is plenty of parking in the drive way and street. A fenced back yard and back porch to sit if desired. We did not make use of this but could have. I would definitely stay again if I was back in Seattle. Its a pretty central location with easy access to down town and other important tourist places :):).
