I enjoyed the duration of my stay at Brian and Kylie's. The room is exactly as described on their page, everything was clean and tidy and included little helpful things like a map of Seattle and literature about things to do in the area.
I was staying for a convention, and this location is about 15 minutes away from the convention center. I would recommend future guests to stay here as long as they don't mind the fare (On average 9-15 dollars when this was posted).
Another reviewer mentioned that they could hear footsteps above the room. This is true, however this should probably be expected. I heard no other noise during my stay, so as long as you can handle footsteps you should be fine.
All in all, 5/5, would stay again.
