last minute booking… what a surprise! Beautiful hotel and location, excellent service. Some of the hotel is a bit dated but was nostalgic for me. Kinda like Hawaii 5-0 old series feel. The view was incredible!!!! Will be back when the wisteria is in bloom across the street as well as to enjoy the beach!

fabulous location, helpful staff but hotel itself needs a good refurbishment, carpets dirty and smelly, paintwork worn. Other floors of the hotel might be better but the foor I was on was way overdue for a spring clean.

Disliked: Cleanliness
They advertised having several restaurants one of which was the buffet which they charge over ¥5,000 for and they weren't even serving anything other than dessert and one type of meat even though they advertised it as having many different types of food. Only one of the other restaurants was open and there is only one other restaurant in town that serves dinner. The rugs and sheets and everything were stained and the hallway rugs looked like they hadn't been cleaned since installation 30 years ago. The onsen and service was good but did not make up for the false advertising of everything else.

Le staff a été très gentil mais certains manquaient de formation. Le bâtiment est mal entretenu exception faite de l'étage de la réception. Les tapis et les murs étaient souillés et tachés . La chambre avait une odeur désagréable. Le site du côté de la baie était plutôt jolie mais l'environnement du côté urbain n'était pas très convivial. Malgré la publicité de l'hôtel le bar était fermée, la piscine sans eau, la terrasse fermée, le balcon de la chambre inaccessible, aucune facilité pour la plage. Nous étions dans un environnement captif qui n'offrait pas d'activité et de service à proximité. Très déçu de notre séjour je ne recommanderais pas cette hôtel.
