Calling this a "vacation home" is at best an understatement, and at worst completely misleading. This is a magnificent home belonging to the best friends you wish you had, who have invited you to stay while they're away -- people of impeccable taste, able and willing to anticipate your every need.
Bring only your clothes (if you must) and whatever food you plan to cook (available in the nearby market). Everything else, from condiments to bandaids to....you name it...is there for you.
My wife and I stayed here for a week -- just the two of us -- and it was one of the most relaxing vacations we've ever had. From the morning, when we had our coffee on the waterfall deck; to the evening, when we grilled our dinner and ate at the outside dining table; to the nighttime, when we sat around a small fire outside soaking in the sounds of the river; every day was perfect from beginning to end.
One day we hiked in Sequoia NP, but the other days found us wandering the nearby hiking paths, meeting the wonderful neighbors (entirely invisible unless we ventured off the property), and absorbing the natural beauty surrounding the home.
Expensive? Compared to what? The mental peace provided by a few days' stay here is beyond price, and something we've rarely encountered elsewhere. That's why we've already booked our next week's stay, in the fall.
Oh, and if you do go, take Chris' advice on where to eat and what to do. He's spot on. And say hello to Fred and his lovely wife Maria, the home's welcoming caretakers.
