This was our first stop on our honeymoon to decompress and just relax. It was a great choice. There's a lot of good things that are close to the house, like Topanga park and the nearby Malibu pier and beach. There were other places in the area, but this was close to the PCH and had a great view, so we splurged a bit.
The guest house is attached to the bottom of the main house on the cliff. It's a little nook with a great view and sounds from the ocean, but you won't hear traffic which is great. Tatiana left us a free bottle of wine which was a nice gesture. There's a good, basic breakfast/lunch joint down at the bottom of the hill, along with a simple liquor store. The gas station nearby has some other basic necessities like decaf coffee if you need it (the kitchen has regular coffee, creamer, tea, oatmeal, etc. if you fancy).
Tatiana kept us up to date on some power issues in the area. It was a routine upgrade, and the power was out overnight and into the day a bit. Nothing in anyone's control really.
You'll definitely want to get a car if staying. Parking was easy and close. There are not a lot of Uber or Lyft drivers out here, either. On a weekday night there were 2 or 3 in the area available at most.
Overall, we enjoyed our stay in the house and in Malibu and would recommend to others.
