Antonia was incredibly helpful during our stay in Santorini. She helped arrange for transportation to and from the port, as well as recommending rental services (for ATVs) and sights to see/where to get the best value for our money (such as the day trip to the nearby Volcano and Hot Springs, which we ended up booking). She always responded to any questions we had, and our stay in Santorini would not have been the same with her help.
