We had a great time at the oceanfront apartment. The ocean is just outside and the sunsets were amazing. Edgar supplies all the stuff you need for a trip to the beach - also all snorkelling equipment, which was great.
We enjoyed snorkelling at Kahulu'u, just down the road and also Two-step and Kealakekua bay is not far away (perfect snorkelling, at the latter we saw the resident pod of dolphins). The snorkelling is also fine just outside the door - in calm conditions that is (be carefull og the lava stones).
