The studio is really nice and exactly as on the pictures! Very clean, comfortable and modern. The view from the terrace is stunning. It was quite windy, but very nice :-) Aristidis made us feel very welcome, and was very helpful. Kastro is one of the most charming villages in Sifnos. There are not a lot of restaurants in Sifnos, but you can walk to Appollonia through a paved stairs (+- 20 minutes), and come back in taxi easily.
