Breakfast and dinner were both excellent. The spacious bathroom was a wonderful surprise, and the ReFa hair dryer made the experience feel even more luxurious. The staff were friendly, professional, and welcoming throughout our stay. If you’re visiting Karatsu, I highly recommend staying here, exploring the town, and enjoying the fresh local seafood. We would definitely love to stay here again.
