A vibrant peach-toned facade frames the entrance of Kastro Oia Houses, a charming boutique property tucked away in the historic center of Oia village. A large, traditional terracotta pot overflows with blossoming peach and purple bougainvillea vines, wrapping gracefully over an elegant pastel blue wooden door. Looking out past the terraced steps, the deep blue expanse of the Aegean Sea unfolds.
