Irene is a great host, we had a wonderful time in Santorini staying at hers and definitely recommend it. The place is very good for those, who do not want to be at the crowded touristic places. There is the black beach, just a few meters in front of the house. The island is small, so you can visit each place of your list anytime, there are buses going everywhere. The place was clean and Irene herself even cleaned it for us every day!
