Easy check in, thankful for bilingual staff. Room was clean and quiet. Gym was sufficient, although the WiFi signal does not work in the gym, and the exercise bike is broken. Area surrounding hotel seemed safe. Also a great paved lane along the water goes for miles, with access if you wanted to walk on the sand. The breakfast buffet had many great Korean foods to try, and ample coffee, definitely worth the money! Easy to Uber from the airport. Did take an Uber about 15 minutes to be available when I wanted to leave.
