Spent an amazing night at LiVeMAX Resort with my girlfriend. The hotel is definitely far from the station, but they offer a shuttle at check-in (3pm) and check-out (11am).
Beautiful room (we had the Premium twin). Beds are comfortable and pushed together to be like a King size. Everything is new/clean. Loved the private outdoor bath.
Swimming pool and onsen facilities were great. The dinner/breakfast buffet was good. We also found the staff to be extremely friendly and helpful (even more genuine feeling than the usual good service you expect in Japan).
Kisami Ohama Beach is about a 15 minute walk from the hotel. Some of the walk is on the side of a road, with no sidewalk, but cars come infrequently and it didn't feel unsafe. Kisami Ohama Beach is beautiful and we spent most of the first day there. On the day of our checkout, we were dropped off by the check-out shuttle at Irita Hama Beach (instead of getting off at the station), and loved that as well.
Overall, extremely satisfied with our stay. If you are aiming for a relaxing, laid-back trip then the remote location shouldn't be a negative, and I think you'll have an amazing stay.
