Perfect apartment for 2 people in a thoughtfully laid out traditional white washed house. Space is cleverly used and the house has everything you need. Kostas and Maria are excellent hosts and are very helpful and hospitable. Kastro is a wonderful and interesting village. There are three locations for swimming near by at Seralia (small beach), church of the seven martyrs ( large flat rocks) and Panagia Poulati ( large flat rocks), the furthest of which is no longer than 30 minutes walk via the walking trails. A perfect holiday. A map of Sifnos, bought in Apollonia, detailing the trails was really handy for walking round much of the island using the apartment as a base. Best holiday I’ve had.
