WELCOME TO CHATEAU DU MER BEACH RESORT

The beach house could now accommodate 10 guests, six in the main floor and four in the first floor( air conditioned room). In addition, you can now reserve your vacation dates ahead and pay the rental fees via PayPal. I hope to see you soon in Marinduque- Home of the Morions and Heart of the Philippines.
