We were there for 11 days in early May, the weather was about 10 degrees cooler than Fresno for our entire stay (about an hour away). It's close (1-2 hours if you take the north vs south route) to the Sequoia parks/forest, and there's a big cat sanctuary a few miles up the road.
The house itself is pretty simple, but did have basic essentials (oil, condiments, several seasonings, popcorn, granola bars, coffee, tea)- enough to get you started on day 1. The kitchen also had a good supply of pots, pans, mixing bowls, etc, if you intend to eat some meals at home like we did.
The house also had body wash, shampoo, conditioner, laundry soap, lotion, kitchen soap, etc. There was a hearty supply of towels, and the hosts offered to refresh them due to our long length of stay, but we didn't even go through them all (although, to be fair, we are a family who reuses the same bath towels a couple times).
There was a nice wood stove, and the essentials needed to get a fire started, we made smores on one of the coldest nights.
The land itself, it's gorgeous, with near 360 mountain views, the only place that's blocked is where the host lives, slightly higher up on the mountain. We saw all kinds of creatures on the property- quail, little lizards, bunnies, many other flying birds, owls; the owners also said foxes and bobcats sometimes. The 4yo loved it.
The hosts were very responsive, were able to suggest good local places to eat, but were also respectful of our privacy.
