Such an incredible experience. Wonderful hosts, a weekend that will leave you feeling refreshed and inspired.
Airstream was really well ventilated and didn't get too hot. Shower and toilet worked great, and though there's a faint chemical smell you can bring some diffusers to mask the smell. We had no problem taking our 98 sedan up the hill though we preferred to park at the bottom and just walk up 10 mins if we weren't carrying much with us (it's a lovely walk, sometimes you'll be joined by their horses!). Airstream has all the basic cooking stuff and a decent sized fridge.
Location is right near one of the main malibu beaches and there's a cute shopping center 15mins away with everything you'd need (grocers, coffee, restaurant).
Will be coming back for the peace and quiet, stargazing and great hospitality!!
