I must mention the room rate (price) for the first of all. Considering all the aspects, no one could complain about the price they have.
Their cleanness was perfect as well as the kindness and willingness to assist customers from the staff were more than enough.
Yes, it's a bit old facility (but renovated properly) and a bit out-of-down town so you may need to rent a car but it's was okay for me.
I also would like to mention their breakfast. As a Korean (with 2 children), it was more than perfect. I even felt sorry for the service I got provided way more than I paid. (but please note that I'm Korean. If you're a foreigner, your selection for breakfast could be a bit limited. They do serve bread, coffee, and egg but mainly, it's Korean traditional breakfast.) but still, no one could complain about breakfast considering the price for the breakfast.
I highly recommend this hotel and will surely visit again when I travel Jeju with my kids.
