Udo used to only stay at guesthouses, but this time he made a reservation at Hundert Hills. Since it is an island and a beach, I honestly thought it would not be well maintained, but I was surprised by how good the condition was, without any bugs, dust, or rust. Perhaps because I didn't have much expectations about Jeju Island resorts, I felt better about this place. The bedding was really clean and fluffy without any dust, and the air conditioning and heating systems installed in each room worked well, and there were no issues with the lights flickering or making noise, so I had a very comfortable and quiet sleep. It was an ocean view suite type B and both rooms had queen size beds, one with an ocean view and one with a tree view. There is only one bathroom, a shower booth, no bathtub, and the sink is outside. There is a kitchen, but cooking is not possible. The Hundertwasser Museum, Hundertwinds (cafe), and Café Dolkan are highly recommended. There is a 24-hour mini convenience store next to the front desk. I had a nice stay.
