Jackie and Nikos's place has an amazing view and the location is impeccable! A handful of nice cafes, restaurants and gift shops are within walking distance. And some of the places of interests (the castle ruins, the Amoudi Bay, the sunset viewpoint, etc.) are walkable as well (around 15-25 min). The bus stop and the taxi stand are also close, so it wouldn't be difficult to take a day trip out of Oia. The apartment is perfect for a couple or a solo traveler in terms of the size.
Jackie and Nikos are superb hosts – very responsive and helpful. My luggage was lost and Nikos kindly helped me communicating with the lady at the airport. There were two electricity black-outs during our stay and Nikos helped us solve the problem immediately.
Overall, it was a great experience staying at their place and I would definitely come back again if had the chance.
