Two friends and I stayed at Mrs. Mania's house in Sifnos for 4 nights. The house is a fantastic unit located in a vernacular settlement of Sifnos -- houses of this type are excellent examples of "anonymous" architecture and are unique to Greek islands. The interior is full of traditional objects like old portraits, furniture, plates, etc. all of which create a unique atmosphere. The view on the top of the house is one of the best views of Sifnos you'll find. The house is located in Katavati which is very close to the capital (Apollonia); you can either walk there in about 15'-20', or drive in less than 3'. There are three great super markets just right in Katavati, so you'll be able to shop anything you need for the house (e.g. coffee, breakfast). The surrounding is extremely quiet, and even though it's full of other houses, you'll still get the sense of privacy. Overall, I highly recommend Mania's house and I would definitely consider staying again in the future.
