The Ostraco Houses is a small complex of beach apartments right on the waterfront, in the small village of Pachena, on the island of Milos, in Greece.

With its dentelated coasts, the predominance of white and blue, its sandy beaches, its monuments revealing the island's contribution to the ancient as well as modern history of Greece, Milos is the fifth largest island in the Cyclades and one of the most beautiful in all of Greece. Its shape resembles a horseshoe, as the two sides of the island are joined by a narrow isthmus. It has one of the safest and largest natural harbours in the Mediterranean.

Milos is known as "The Island of Colours" thanks to its volcanic origin. Its fame has spread thanks to the Aphrodite of Milos, the famous statue that is better known as the "Venus de Milo." It is a versatile summer destination thanks to over 80 splendid and quite different beaches with waters of every imaginable shade of green and blue, and historical sights to be seen, offering something for everyone.
