This place was a great stay near the Kamari black sand beach - only about a 5-10 min walk tops to get to all the restaurants by beach. Ιφιγενεια wasn't there when we visited in May, but her cousin Giannis picked us up from the airport when we got in, also helped us rent a car that allowed us to get around the island and visit Ancient Thira (just up the hill, would recommend visiting!), Fira, Imerovigli and Oia. There is also a small grocery store about a 5 minute walk from the house that should get you all the basics you'll need, otherwise all the food in town is delicious - you can pretty much stop at any restaurant along the beach and you can't go wrong. Had a great stay here!
One note that all visitors should be aware of - if you are going to be renting an ATV, scooter or car, there is a new law in Santorini as of May 1st, 2018 that requires you to have an international license, so you'll want to look into that before your visit!
