I just wanted to say a big thank you to Mr. Koga. He accompanied us to the express bus stop, waited with us until we boarded and even translated to the driver to make sure we reached our destination to Rinku town station. He was so helpful our journey was so much smoother. I truly appreciate his help.

We enjoyed indoors and outdoors hot springs. we were a bit disappointed with a lack of toilet in the room. The location near the sea is very nice.
