  • It was the perfect holiday.

    Every summer vacation, we stay at this seaside Hotel.The Rooms in the East Wing and the amenities are truly wonderful, and we always look forward to them.One small disappointment was that last year there was a bottle of water by the sink in the bathroom, but this time it wasn’t provided.Also, the staff’s service was excellent.In the morning, when my child and I were swimming in the sea, I’m not sure if it was a staff member or a volunteer, but someone was carefully picking up litter on the beach.It was wonderful. Thanks to that, there wasn’t any trash at all on the beach in front of the Hotel, and we could swim comfortably.We’ll be back again next year.We hope it will be even more upgraded—haha.

  • We had a wonderful stay.

    When I stayed before, I felt the meals had changed a bit after it became part of Chateraise, so I hadn’t visited for a while. This time, after a long break, I stayed again and found the buffet back to its former variety—everything was delicious. With a rooftop pool, outdoor pool, and indoor pool—and the beach right in front—the kids were thrilled. On the Onsen floor, there was also plenty of Chateraise ice cream available, which they really enjoyed. It’s a Hotel with excellent family-friendly facilities, and we’d love to stay again.
