The Redwood treehouse is a really lovely place with a great story behind it (read the scrapbook that you’ll find in the house). You will have a few neighbors nearby, but I found this place to be great for solitude and privacy. I was very glad that other reviews told me about the path from your parking place to the treehouse (about a 5 minute walk down a beautifully wooded mountain path), as well as how dark it gets at night (you’ll need a decent flashlight if you plan to go and come after dark).
The treehouse is a magical, wonderful place that I fully intend to stay in again. I’ve already recommended it to friends. You should be aware that’s it’s not a 5-star hotel. Some reviews here seem to think that a cabin in the woods would have all the amenities of a big city hotel. As long as you realize that a small house supported by Redwood Trees isn’t the Park Plaza, you will love this place. Mary Jane and Marty were so kind and helpful with anything I needed, and their hospitality was a big part of the experience for me.
