My boyfriend and I spent a long weekend in the Cedar Treehouse, and had an amazing time. Would definitely consider visiting again. The location is very quiet and secluded, and while there are other people who stayed on the resort, we rarely ran into them. We partook in the sauna and spa package, which was extremely relaxing.
The Treehouse itself was perfect--exactly as described. It was perfect for 2 people, but the couch downstairs was convertible, so you could easily fit another person. We loved the skylight. [Un]fortunately, their internet service provide experienced an issue while we were there, so WiFi was out for a couple of days (and cell service is little to non-existent), but to be honest it was a blessing in disguise and helped us truly disconnect from the outside world. We enjoyed relaxing in the pool and jacuzzi, and just enjoyed the environment overall.
Tea and coffee were available in the treehouse, and a tea kettle for hot water. There was a jug with their delicious reverse osmosis water. There are cups/dishes/silverware/pots/pans. We made sure to bring up food, and there was a small mini-fridge to store everything. We did go into town one of the days, which is just a relatively quick drive down the mountain (approx. 10-15 min to Aptos Village).
Again, had an amazing time and would highly recommend!
