I have a two bedroom apartment at Marina D'or in Orepesa.
It is a fourth floor apartment with shared pool. However, it is 2nd line just 5 minutes walk to the beach.
Fully furnished with lovely spa bath and shower, air conditioning, tv and fully equipped kitchen.
the city of Valencia is 45 minutes away, and the historic city of Castellon about 20 minutes.
Have a look on the Marina D'or web-site for information about the place. Its home to Europe's largest salt water spas, and has everyhing you could possibly need within walking distance
