This is a diving hostel, dedicated for groups and individuals doing diving sessions, and Sea Friend seems to be the biggest in the area. They are efficient and clean. Facilities are rather basic but this is to be expected in such a facility. It gets the job done. The option to dive with their own people makes the trip super affordable as a dive location. I thought the food options were affordable at their canteen, average alongside the other places in Aharen. The breakfast is rather basic Japanese fare (with a good variety and quantity) and is all delicious.
Everything was good!
Also, no need to book the fast ferry - they are set up with a schedule that practically syncs up with the slow one.
