We had an excellent stay. While we did not get to meet Maria the property manager personally, we were able to meet one of her colleagues (also named Maria), who was extremely kind and helpful. She provided us with in-depth information about different parts of the island, made recommendations, and helped us book a beautiful sunset sailing tour. We did not expect to have a concierge service like this with Airbnb so we were very grateful.
We had to go down many steep steps to reach the cave and only one porter was provided, meaning that one of us had to carry heavy luggage down and up the steps. This was the only disappointing part as we would have been happy to pay for a second porter if necessary. I'm confident nonetheless that when we return, Maria will be able to help arrange this for us but better to request for it in advance.
