Well, I only stayed one night in Busan and I was very lucky to have chosen this hotel. It was not only the best spot to choose, as a lot is around the hotel itself, including the beach, but the hotel and its view. I would recommend to choose a room with ocean view, it is breathtaking and if you have one with a balcony, what else is to ask for then to be able to enjoy the sunrise and sunset. The staff I met was very friendly and kind. The room I stayed in was well designed and the bed was cozy.
Thank you Grab the Ocean for my stay and whenever I will travel back to Busan, I will stay at yours, for sure :)
