This is a wonderful stay for a family. It was my mother, my twin daughters and I with two rooms in one of the cabins. Full sized beds with clean linens on the ground and two twin sized bunks on the wall. Rooms are small, but it's a hostel, so please take that into consideration.
Just a microwave/dorm fridge so you won't be doing a lot of cooking, and there aren't many options for food close by because of the location. But the views are magical, the beach is a small/easy hike down the cliffs and I could have sat and listened to the waves just outside our windows all day and night. Despite there being many dorms/buildings things were pretty quiet on the campus, and it's a good central location to do things around on the coast. I would highly recommend this stay, we had so much fun and made a lot of memories!
