We stay 2 nights at this new hotel (2016). Every things is clean, nice and new. We loved this hotel. The rooms are located in a few separate blocks. Every block has its own lift. Good wifi in the room. Clean towels provided. Toilet and bathroom are separate - this is a big plus for the hotel. Most hotel in Korea do not use shower curtain and the bathroom floor is alway wet.
While staying on this side of Jeju, we travelled to Manunggul Lave Cave, Seongeup Folk Village (filming locations for many popular Korean drama). Short distance to Seopjikoji (scenic view of the sea and filming locations for Korea drama). And enjoyed good/cheap seafood while driving along the Shore Road. Accidentally, we found a old fortress - Byeolbangjin Fortress along the Shore Road.
We wanted to go to Udo Island and I choose this hotel as it is near to the the ferry. However due to lack of time, we did not go to Udo. So if I am back to Jeju, I will be back at this beautiful clean hotel.
I think the other 2 reviews are referring to a different hotel. This hotel is in a quiet area in Seongsan, Jeju Island. It is not near the main road (see photos by the hotel). The surrounding area are farm land and full of greenery. There is a lack of restaurants nearby but within walking distance a mini-shop where you can buy instant noodles, drinks, etc..
