The Anini beach house is great, only a few meters from the beach with shaded areas and very shallow water perfect for young kids. There is snorkeling by the rocks close by including multiple turtles when we were there. It's also very relaxing to stroll on the beach early or late in the day.
You can also contact local companies to deliver a stand up paddle board for free if you rent for 3 or more days, we realized it too late but that'd be a great area for that as the sea is very quiet typically in the morning and evening.
The house has plenty of space and easy to live in for a family of 4. The downstairs changing/beach gear area is very convenient as well as the outdoor shower.
We had a great time.
