Katerina and Yannis provide wonderful mini houses with an "open bar" kitchen garden with eggplants, lemons, pomegranates, peers, oranges, etc. depending on the time of year. We had a surprise gift almost every morning (fresh milk, fresh fruits, traditional cheese, pastries).
The place is close to Artemonas and Apollonia, which are the nodes for almost every walking trails of the island. It is also practical if you won't to travel by bus.
Perivoli is for us the perfect spot in Sifnos ! <3
