We only managed to stay a night and did not get to use its osen facilities or have breakfast there. We would love to try this hotel again. It was clean,and the staff were friendly. It is located near the train station which is 10mins away from the Kansai International airport (Provided you take the correct train! >.<) The hotel does provide free airport transfer but do check the timings as it is not frequent and not for the whole day. We caught the first bus leaving the hotel for the domestic airport.
There were many shops nearby and also a street with quaint little restaurants. Would definitely return.
