I am uncertain as to how to rate this hotel. One impression we had was that this hotel was understaffed and shorthanded. We arrived in the midst of a minor situation having lost some of our luggage on the way from the airport. With lots of help from someone in the bus terminal and a bit of coordination from the hotel front desk we located our luggage and formulated a plan for retrieval.
This involved going to the bus station, about a 30 minute walk, relatively late at night. We were hoping the hotel might offer a shuttle van to help us get our luggage, which would have the proper response from a 4-5 star hotel, but they didn't. So we ended up walking.
There were other similar instances where the service came up short, and it just felt like they were understaffed.
The room itself was nice enough and featured a separate jacuzzi bathtub with a view of the pool/ocean. That was a nice touch. The outdoor pool was warm enough for winter swimming, as advertised, and this was also very pleasant.
We tried the room service once, which was quite good, but expensive as other reviewers have noted. There isn't very much around the hotel in terms of shops or restaurants, but there is a convenience store almost across the street. This was super helpful.
Overall, we might try this property again if we are in Jeju, but it might better to try a different property that might be better staffed.
