I was on a roadtrip with my sister when we stayed in Jay's awesome treehouse for two nights. It was the first time for us to stay in a treehouse and we totally loved it.
The treehouse has a lot of light, is really clean and has a very well-equipped kitchen.
Jay provided us with lots of useful information about Seattle and it was great to hear from him about the development of the neighborhood.
The treehouse is in a beautiful quiet residential neighborhood, we really liked this. If you don't have a car getting downtown takes approximately 35 minutes including a 15 minutes walk from the treehouse to the station.
We would definitely recommend staying in the treehouse if you want to discover Seattle and it's beautiful surroundings.
