We loved staying in Kastro during our time on Sifnos because there is lots to do around there and it is centrally located. The view from this listing’s balcony is stunning. However, we weren’t able to enjoy the outdoor space because it was SO windy while we were there and this air bnb is pretty much on a cliff side with no protection from the wind. As a result, we ended up not spending too much time at the air bnb, but it met our simple needs of a comfortable and private place to sleep. Our host was very responsive and offered great recommendations of places to visit on the island.
