There are cottages that you can rent made by the local government and there are also Hotels where you can stay.

The time we went there, it jumped pack since it was a holy week. Upon entering the Hotel, the entrance was their buffet or the restaurant area. They don't actually have a lobby area. Their buffet cost around 400-700php. Don't miss their buffet because they serve really good Ilocano and Filipino food.

The beach is open to the public, they can enter the premises even they are not staying in the hotel. Don't expect that the beach is really clean, I did not enjoy the beach side because I can see liter on the shore and in the water. What you'll enjoy are the calm water and the fine sand,
The hotel has a 5feet pool and a kiddie pool.

There are other amenities on the beach front. Thye have Kayak, Jetski, Island Hopping, and Paddle Boat.
If you are tired in the waters and other beach activities, I found a view deck 20feet away from Santiago Cove.
The deck can give you the whole view of the cove, as well as the mountains of Ilocos at the distance that serves as the beach’s background.

Overall, My Santiago Cove Hotel stay was good, their amenities were good and well maintained. It was another fun-filled vacation with comfy rooms and clean bathrooms. It's just their service must be improved in the future, their staffs are not attentive and approachable or maybe because of the language barrier. But It's a good and affordable hotel, I hope they'll improve it for future rendezvous.
