This guest house (minshuku) is not hard to find with GPS. If you are not coming here by a rental car, you get ask the operator to come pick you up. In fact, I saw the hostess waiting for me at the pier (and also the uni-kun waving and wiggling to the passengers of the ferry :D).
It is clean and cosy. There is no individual bathroom/ toilet in the room but it is very close to the room anyway. There for 2 toilets for guys and girls. The bathroom has square tub like you see in Japanese drama. Don't miss the food there because it was awesome!!! The grilled abalone and the hot pot with uni are their signature dishes! The hostess was very nice. She talked to me a lot and asked me how I found this place. I told her i saw it in one of our local travel magazine. She then quickly grab the magazine with joy asking if that's the one. She also shared her stories and tell me what to do on the island. I thoroughly enjoyed my stay there. More
