We (myself, my wife and our pet dog) had a wonderful time!
We stayed for 4 days during the chuseok holiday, and highly recommend this hotel. It is run by a very friendly family, who helped make our stay pleasant and enjoyable.
The facilities for dogs are very good. There's also good fun to be had with the karaoke machine, darts, and virtual golf machines!
The location is a short drive from mallipo beach-front area, and a little further you will find lots of great hiking opportunities.
