Me, my wife and our 2 kids (5 and 8 years old) stayed there for 5 days (Easter 2017). This house is an old stone house well preserved with respect to the suroundings and the traditional architecture of the island. It has all the basics to have a pleasant stay, but don't expect luxuries. Another thing to bear in mind is that you have to walk approximately 10 min using an easy (though uphill) and very beautiful path from the central road to reach the house.
There is another path also from the house to the pedestrian road towards Ioulida or the lion of Kea statue (about 5 to 10 min). When you reach the pedestrian road it takes 5 min to the lion of Kea (which is visible from House's veranda) and 10 to 15 min to the centre of Ioulida.
If luxuries is not your priority, but peace and beauty of Greek nature is, If you want to discover what real life means this is the place for you.
In addition, Antell was very helpful and kind giving us great advices. We certainly be back again...
