We stayed here in September 2021. The place is nice and cozy; a little tight in a couple of places, but great for 2 (maybe 3) people. The ceiling is on the lower side; I'm just under 6' tall and could touch the ceiling easily. If you're on the taller side, keep this in mind.
Keith and Audrey keep the place stocked with cooking stuff (spices, pots, plates, etc.) and toiletry items (towels, toilet paper, etc). There's a folder with information on checking in and out, garbage, and so on. This folder also includes some local restaurant menus and tourist guides.
Parking was great. We were able to use the carport which kept the rain off of our rental car. There are a couple of seats and a table next to the entry door if you want to sit outside.
The house is reasonably close to I-5, and near to the Museum of Flight and Kubota Gardens. Via the 5, we were only a handful of miles from most areas that we wanted to visit in Seattle. Additionally, we were close enough to SEA-TAC for our return home that we didn't have to wake up too early for a long drive to the airport.
