The Jacuzzi was merely warm. Closer to room temperature. We were very disappointed and left after the first night. The owner uses a very seductive photo of the jacuzzi and was the main reason we chose this place. They have it on a timer that stops at 8PM. I have an 8 person outdoor jacuzzi in my back garden that also runs on a timer. It runs for two hours and the water can get very hot. When we turn it off to just soak, after twenty or thirty minutes without the heater running, it is much, much hotter than this one ever was while running. I think the Greeks and perhaps the Europeans in general have a very different idea of what a Jacuzzi is supposed to be. Otherwise, the place is clean and charming. I was promised a full refund and did not get it. Got a partial refund instead. Never met Elefheria. All communication was by text and email. Need a car for this place, it's remote. The car parking is about a five minute walk. Santorini was the last stop of a month long trip with my kids and we really wanted a jacuzzi because the outside temp in May was a bit chilly. This was a disappointing way to conclude an otherwise fantastic trip.
