We had a lovely stay at Popi's house. Very well located, in the heart of Chora but in a quite area, the house is nice, clean, spacious and fresh (air conditioning in each bedroom).
Balconies in both bedrooms on the 1st floor, and a small table in front of the house (in the quite street) allowed us to enjoy the outside atmosphere.
Popi is the very best host ever : careful, helpful, fully dedicated to her guests, giving us fresh food from her farm (eggs, fruits, vegetables..) and cooking wonderful original breakfast for us every day ! She also organized taxi at arrival and departure, and was there to welcome us even though we arrived at 3h50 at night !!
Astypalea is a beautiful island that is worth discovering with a car (beware to book it early as there is not so many rental agencies on the island). Many beautiful creeks, quite isolated (but always with a taverna !). Local people are extremely nice and welcoming (everybody says hello in the street).
We spent many times in Greece since the 80's, and thanks to Popi, we found again the local spirit and hospitality !
