The host is really kind. He answered my questions right away, and even though I asked late at night, he answered right away. The condition of the house is new and I am very satisfied.
The house is about 200 meters from the beach, so you can walk there and play in the water. There are also restaurants within 5 minutes by car... I especially recommend Sora Hoejib.
Anyway, I am leaving Jeju Island after a week of being very satisfied.
Thank you, host!
