The location of the house is incredible : right on a beautiful sand beach, and from there you can go without a car to either Kastro (1h30 walking, beautiful coastal hike) or Chrysopigi monastery (about 20/25min walk). If you like to walk and swim, that is an excellent spot!!
The house itself has an awesome terrace overlooking the bay. Inside, if you’re looking for the best design and comfort that might not be your spot; but it’s functional and has all the basics.
I was there in December so completely off season. My following comments might have to do with that, and probably during high season things are different.
Kryaki wasn’t there, so she had a local owner of a Taverna (situated 50m from the house) take care of things for her. And honestly the whole time I had the feeling that I was bothering him and his wife. Communication was simply impossible, as they spoke almost no English, and they clearly had no intention of helping me with anything. Things like buses timetables, opening hours of the minimarket, calling a taxi, fixing the internet etc, I had to find out on my own, or to text the owner who was in Athens. So I think that could be good for the owner to ask Nikos if he hates having tourists around during the off season -in that case it would be better to work without him...
In high season that would not be a problem, as I suppose you can ask to other people around.
