We ended up here to attend a U2 concert and the accommodation was exactly as described. My description would be a little remote but after battling California traffic, it was a quiet place to unwind. The view is spectacular but the landscaping is a little unpolished and your outdoor area is essentialy a 200-300 sq foot deck when staying on the lower level of this duplex. Ling and David were there a couple days and offered their laundry facilities to us. With long term stays it could become a bit of an issue if you are packing light.
The nights are quiet and cooler with the altitude and location but we did encounter a family with two young children staying above us and the with it being a wooden structure, there was no sleeping in.
As in our case, the lower unit is best for couples because it is more like a large suite without walls to the ceiling and curtains for doors. If your shy, the bathroom isn't too private. The wifi worked well and we only turned the tv on once to get the morning news. The apartment was well stocked and there wasn't the usual leftover unused items from previous renters.
Malibu has a small town feel with great restaurants and shuts down relatively early.
If your looking for a getaway and some one on one time, possibly catching up with your reading, this is the place for you. Far enough from the LA caos but close enough to trip into Hollywood if you want your fill of materialism.
So take this review with a grain of salt because we live on an acreage in the Rocky Mountains and aren't used to sharing. Would I stay again if travels brough us back? Yes.
