We loved our stay here. The rooms were clean and had everything we needed, with a great view. The host went above and beyond to help us make the most of our short stay in Santorini, organising quad bikes and helping us plan our day and see all the sights.
As advertised, it's definitely walkable to Fira, probably 10 to 15 minutes, just be warned that there is no foot path so the walk home late at night should be taken carefully.
