Kostas and Katerina's house is located inside a traditional village which is pedestrianised and very tranquil. The only sounds were often the church bells and the occasional chatter of locals going past the house. As it is very quiet we slept really well during our stay. The village feels away from it all yet it is very close to Apollonia with it's buzzing restaurants, bars and shops. The house has a lovely, big garden which was great to return to in the evenings to enjoy a glass of wine on the terrace. The house itself had everything we needed - a well equipped kitchen and a great shower. The outdoor shower was also a great addition. The house was only a few mins from a mini-market where the owner could order a daily, fresh loaf of bread should you require it! Although we didn't get to meet Kostas and Katerina in person (they were in Athens at the time), Kostas was very responsive to any queries we had which was very helpful and reassuring. I would definitely recommend this house to anyone who likes a quiet place yet is within 10 mins walk of Appollonia. All in all a great choice for a wonderful three week stay in Sifnos.
