The value for money is good. It seems maintenance is needed.
I rented a four-person room. The facilities are old, and the electric kettle and refrigerator are very worn. There was no mirror in the room, and even though it was a four-person room, there was only one bathroom, which was very inconvenient. The beds were clean. The breakfast was reasonable for the price.

I was assigned Building C, so it was a bit inconvenient to go to breakfast, but you can reach the main building via a connecting staircase from Building B. At night, it would be nice if the B building entrance had signs showing the way to Building C. Please mark those two items so they are easy to see. The room is spacious and the cleanliness is acceptable. Breakfast is fine for a quick meal. If you compare across several sites, there are some cheaper options that include breakfast. It was a bit crowded because there were group travelers, but with about 250 rooms, reservations were possible. From the C building hallway you can see Hallasan, and from the terrace you can see a distant sea view.

It would be good to have signage on Building B's entrance showing the way to Building C at night. Please mark those two things so they are easy to see. The room is spacious and the hygiene is fairly okay. The breakfast is simple and easy to enjoy. On some booking sites you can find cheaper rates that include breakfast. It was a bit crowded with group travelers, but there are about 250 rooms so reservations were possible. From the C-building corridor you can see Hallasan, and from the terrace you get a distant sea view. Small soap, shampoo, conditioner, and body cleanser are provided.
Great value resort. Good location and a satisfying breakfast. The cleaning is okay, but there is some mold in the bathroom grout; if you can overlook that, I recommend it.

The room is reallllllly spacious. I rested comfortably.
