Simona's place is amazing and she is the perfect Airbnb host. The views are to die for and the solitude you have is priceless. Her home is beyond comfortable and has everything you need. We were there in June and the majority of the time we didn't even use the air conditioner, we used the ceiling fan, but is great that the a/c is there. The closest little private beach, a beautiful azure cove is where you should park yourself. It's right at the bottom of the road up to the house. Watch the Italians to see how to get down there or go to the flat pebble beach just to the left of it. Definitely eat at Azzurra Makari. The seafood is fresh and great. San Vito Lo Capo beach is a true Italian beach experience, it looks like chaos, but is orderly. Rent a lounger and enjoy the sandy beach and the views there.
BBQ grill: definitely the best BBQ we have used in all of Europe. Simona has everything you need to build an amazing fire. Mio market is great. Has everything you need.
Car: you really need an SUV or CUV or something with ground clearance and at the very least front wheel drive. We had a Renault Captur which worked for us.
Lastly, Simona is an amazing hostess. We got a flat tire and our rental company (Europcar) was of no help. Simona found a mechanic who came to the house and fixed our car.
