Oia is beautiful and the place is amazing. Finding the house for check-in was a bit confusing because there are no street addresses - only general directions! The Helios Cave House is beautiful and located in the most iconic spot in Oia. We enjoyed watching the sunset from our balcony with the complimentary wine...we also enjoyed watching the tourists taking photos in front of our door. Our porter, Sunhil, was amazing and easily carried our bags. I highly recommend The Helios House!
