The location of this place was great! It was relatively close to our places of interest (WeHo, Hollywood sign, etc.). Your parking on the driveway gives you great peace of mind but there isn't a plug nearby so be sure to get your car charged before coming. The guest house was hidden in the back of the main house and was nice for privacy reasons. The guest house itself was clean and cozy. Perfect for what we needed. The only comment I have is with the shower. It is pretty short and fixed so there's no adjusting it. At 6'2" when I stand in the shower the water hits below my chest. If you're shorter, this won't be much of a problem.
The kitchen area looked great but we didn't really use it. Fridge was a nice size though and was already stocked with some bottles of water for us.
Would definitely book again the next time we're in LA!
