Martin's place is just as pictured. It's extremely clean, 2 blocks from the buses you need (taormina, messina etc), 2 min from restaurants, BEACH, supermarket...
Good wifi, air conditioning, good light.
Although I never met him, he was mostly very responsive by text.
Overall: highly recommend. Especially for people who want to explore taormina which I find too touristy and crowded. Or, just for anyone who wants to enjoy a beautiful beach. There are both public and private areas where you pay 7-10 euros for a chair and umbrella.
