I loved Haris' Cave House. It is smack dab in the middle of Oia next to all of the pretty houses. Its newly renovated and smells brand spanking new. It was clean and convenient to EVERYTHING. The best part of my trip though was my host! I was traveling alone and he was so nice, patient, and helpful. He told me all of the great places to go and arranged some AMAZING tours for me! He is the person to go to for any of your needs in Santorini, big or small.
