I would thoroughly recommend staying at Katerina's villa if visiting Sifnos. The position is perfect, with wonderful views over Kastro, Poulati, and Paros/Antiparos in the distance. The accommodation was faultless; perfectly comfortable for the two of us staying. Katerina is a wonderful host - even though she wasn't able to be in Sifnos at the time, she arranged for her father to pick us up from the port and take us back there at the end of the stay. He was also kind enough to take us to the supermarket and back in his car, which was a great help. This is a lovely place to stay in one of the most beautiful parts of Sifnos, and Katerina's hospitality is outstanding. I look forward to returning soon!
