So 10/10 would recommend this treehouse....to the right person. I'm assuming that if you've made it this far in the reviews you're a person that is fairly comfortable with camping, either open-air or in a tent. If not, maybe this will be your gateway stay to camping :) Here are some things I think would make this stay perfect. If you're not flying (or have room in your luggage), pack:
1) ear plugs - although its true this treehouse is located on a nice quiet street, it is one block parallel to a /very/ busy main road. And you hear everything - cars, planes, dogs...all of it. If you can sleep with headphones, perfect. If not, and you're a light sleeper (like myself) pack ear plugs. Things quieted down around 3 AM, about the time my alarm went off to go to LAX (of course).
2) mosquito net - I was actually kinda shocked one wasn't provided since you're basically just sleeping open-air style. However, the hosts do provide bug spray (a million thanks!), but this is just a temporary solution to a consistent problem. Even with the bug spray I came home with several (read: a lot) of bites. Also I was buzzed awake a few times throughout the night. Maybe this is a seasonal issue (I stayed in late June), but a mosquito net would have helped immensely!
3) sleeping pad - the little pad to sleep on was ok, but if I had my camping sleeping pad, it would've been plush!
Also just a note on size. The "living"/sleeping area of the treehouse is about the size of a Twin XL mattress. So keep that in mind if you're booking for two people. Had my 6'4" husband stayed with me, we would have been cramped. It's like a two person tent that really only fits one person comfortably.
Otherwise, this was such a cool spot! I grew up with a treehouse and this made me feel like a kid again! There were still some blooms on the magnolia tree, a good breeze and sleeping temperature (low 60s). Loved all the notes and photos from past guests. There was plenty of light to read at night. Also the dogs never barked at me and Dewy checked on me a few times during the evening. Regardless of the bug bites, I'm super glad I stayed here!
