Absolutely love this place. Stayed with my 10 year old daughter as a treat and this is our second time.

Breakfast was very good either buffet or in room service - there was a lot more food than 1 person portion! Staffs speaks English so if you are a bit not sure on Korean language, GoldOne will be a safe place.
Views and the ambience there just superb. So quiet and yet vibrant and place well managed.
Went to their secret garden path and headed to the beach as a late afternoon stroll. A bit chilly but air was so crispy and nature so untouched.
Beddings were perfect for us and they cleaned our room very well.
Lots of places to visit in the vicinity. Our favourites are Seogwipo Olle market in the Old town (10 min by car), Jungmoon beach (20 min by car), Hwangwooji coast.

This is definitely a hidden gem in Jeju and will recommend anyone!
