We traveled to Jeju for 6 nights and 7 days with three families and our dog, and we were all told we made a good choice.
With our 11kg medium-sized dog, we had limited lodging options, but we were able to enjoy a great stay at a reasonable price, even though we didn't have to pay extra for a long stay.
First of all, the accommodation was located about an hour from the airport, so it was quiet and convenient for a family stay. It was close to Seongsan Ilchulbong Peak, Seopjikoji, and Seongeup Village, and there were plenty of good restaurants near Seongsan Ilchulbong Peak, so food was no problem.
The owner seemed to take great care of us, as the blankets and towels were clean and odor-free, and I loved the large bathroom.
And as soon as we arrived, the owner sent us a text message with recommendations for dog-friendly restaurants and tourist attractions, which was incredibly helpful during our stay.
Finally, the road leading from the accommodation offers a view of the ocean, so we took our dog for a morning walk and became close with the convenience store owner, which was really nice.
I'd love to stay here again next time I travel east. Stay healthy, owner!
