Maria's assistant also named Maria met us at the cave house when we arrived with the porter. She was SO VERY helpful! The reason we stayed in Oia was for a front row seat to watch the sunsets (which did not disappoint from the patio). Beware, there are many many many tourists in this picturesqe town, but Maria drew on the map all the places to go on ATVs to get away from the crowds. She is busy, but spent a lot of time making us feel welcome!
