The house is amazing, located at the bottom of the hill which allowed us to enjoy private n quiet beautiful view of Aegean sea n the lovely Oia sunset. We just spent a lot of time seating at the balcony enjoying the lovely time. Though we didn't meet John during our stay, he responded promptly since we made a reservation til we left. He also sent his housekeeper to help us when we needed (esp. being the porter to help us carry the luggage up n down!). His arrangement on the pick up service to/from the port also helped a lot. We recommend John's house if u visit Santorini. =)
