Before coming here, you should be sure what you want. It is really a sort of Youth Hostel, and both the food and the accommodation are basic. Most people there are young participants in the training courses they run, and the place is, quite rightly, geared towards them. There are some private rooms, but they are very simple. Meals are collective and at set times; be late, and there is nothing left.
This all said, it is what you want you will have an enjoyable time. It is the only accommodation in the north of the island, and a quiet and beautiful base for walks into the rain forest and down to the beach. Horses for courses!
