The tree house was great and very clean. It looks like there was a lot of effort out in to it. It doesn't have ANY walls so it's pretty much glorified camping, but in someone's back yard. If there happened to be a bathroom and kitchen area to use that wasn't in the main house then I think it would be much more enjoyable. The host kept asking us to leave during the day because she had things planned that she didn't want us there for. It felt like we were just unwanted guests that she made sleep outside. She also asked us to leave before our check out time at 11:00am because she had something else that she wanted to go to, after she fully knew what time she had originally asked us to check out at. Next time I'm in Seattle, this is not going to be where I'm choosing to stay.
