Sarah was extremely helpful in the run up to our trip and organised the car hire, which was essential for exploring the island, as well as the taxi to / from the airport.
The house itself is large, with lovely views and outside areas for relaxing. The five bedrooms are all well appointed, although we didn't use the separate one by the pool, which is pretty much self-contained. UK Netflix was an added bonus for the children, who also slept in the platform bedroom above the kitchen, which they loved as it was like a tree house.
The kitchen had lots of equipment so cooking was easy.
Others have noted the steps up to the property, which were no problem for us, and the driveway is steep and narrow, which I imagine could intimidate some.
Having the village and the bakery a short walk away was great, and we ate out three times in Megalochori at different places - all excellent.
In short, it's a great place to spend time, but also a convenient central location to explore the island, from Perissa black sand beach in the south to Oia in the north. It's in a 'real' bit of Santorini, with locals living around, as well as donkeys, horses and mules to pet and feed next door! I wouldn't stay anywhere else.
