This place is very comfortable and very clean. You don't need to worry about any distractions, it's totally independent place from others! For facilities, I think the actual condition is a way better than the pictures described, everything's available here! What I liked most about this place was surrounding of this area. There are so many beautiful houses around Karen's house, (absolutely including Karen's house ;) ), and if you go out like 2 blocks away , you can see a beautiful scenery along the lake.
And as to transportation, we had a rental car, and we were very easily go to the main strip. I remember that the 1st St. is the Pike Public Market, and Karen's house is near 32th? 33th? St. you just can go through all the way without any traffics, and you also enjoy more detalis of Seattle during commuting.
Karen and her family was really great to us before and during our staying.
I absolutely want to recommend this place if you plan to travel in Seattle, Karen's place will make you be able to enjoy and feel more comfortable and peaceful Seattle!
