Elvira was very accessible and made it very clear how to access the property ! it's pretty easy but all the details still helped since it was our first time on the island. She's very welcoming, gave us some guides of the island & greece as well as very good restaurant & activities recommendations! I would recommend staying at her place.
Small thing though (which she can't really do anything about) is the wifi connection. Due to the caves, the further down the less you it works. But that's not a real problem when you're on holidays ;)
