The treehouse is a magical place to get away. It's secluded among redwoods, but also a short drive from the greater Santa Cruz area. We spent a few days here over the New Year, and had everything we needed to cook all of our meals. The fireplace works great, and we enjoyed many Scrabble games before it, or curled up with a book while fog drifted through the trees. Highly recommend.
Helpful FYIs: It's a bit of a walk from where you park to the cabin, so keep this in mind when packing. I highly suggest arriving during the daytime, as it can be difficult to find in the dark. (It's also easier to carry stuff when you don't have to use a flashlight.) Cell service is spotty, and there is no wifi. I was successfully able to use a Verizon hot spot for some basic work connectivity, but it wasn't strong enough to stream music or video. (We didn't mind, but if it's important to you, head's up.)
