This apartment is wonderful. The location was amazing - it feels like you are walking through history. The apartment is nestled in the center of walled Kastro. It is a 2 minute walk to a few cafes and ten minutes to a small rocky swimming beach or the rocks at the base of the Church of the 7 Martyrs ( a beautiful walk). The apartment is also just a short walk to the ancient acropolis of Kastro. The island's bus system made staying at this apartment also super easy, as all of the island's villages and beaches are easily connected by bus. Eleni was a wonderfully kind, helpful, and accommodating host. I'd highly recommend this place for a stay on Sifnos and in Kastro.
