Very comfortable and clean family-run place on the quiet side of Kamares.
Antonis was really helpful, let me check in three hours early (!), and gave some excellent tips on what to do on the island.
Restaurants, shops, bakery etc. are all about 15 mins away on the other side of the bay. The accommodation was really quiet, has an excellent swimming spot metres away and gives access to a nearby path that allows you to reach the Cape (20-30 mins total).
This is a great place to start the 6a/6 hike, with the ascent giving stunning views of the bay below.
A really nice welcome to Sifnos. Thanks again!
