Great to stay up on Mulholland Drive! Terrace and view as described and pictured. Short drive to most everything you'd need. Quiet location. Helpful host.
Note however that the price strongly reflects the location and the stunning terrace, pool and view. The room (the one we stayed in - there are several) was more or less the size of the bed - without allowing for bedside tables - and did not share the view (although neither was claimed to). Putting a cup of coffee down was a challenge.
The value overall is reasonable, but I would suggest that 40% of what you pay is for the terrace and view, and 10% for the Mulholland address. Benchmark for this comparison is a Laurel Canyon address (1/4 mile away) I stayed in two weeks beforehand.
