Wonderful place. Poppy's hospitality will make you feel at home and comfortable once you meet her and step inside the room. she is always available for any help you need. In my opinion the best feature of the house is the big balcony. You can sit there all day and look at the ocean. The sunrise in Aegean is alone worth the money.
location wise it is also superb, you can walk to the main bus station of Santorini, Fira. From here you will get bus to any location in Santorini. The place has small kitchen to make breakfasts, good wifi, comfortable beds and chairs to enjoy the view from the balcony. Poppy's friend Panos also provides cheapest airport transfers. If we ever come back to Santorini we will not look anywhere else. :-)
