This hotel-resort is well loved by young Japanese families. For a tourist passing through Uno area it is 20 minutes from Uno by bus or taxi. The hotel sits alone in this area with a beautiful beach. Staff is very helpful

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!

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.

We wanted to visit Naoshima, and at the time this hotel seemed like a decent choice. What a disappointment! Hotel is stand-alone, 5 bus stations from the center of Ueno, without any restaurants near it. Hotel is '70s architecture' and so are the rooms and the decor. Carpets are dirty and worn out, dirty glass front leading to terrace (with amazing sea view), poor breakfast, no control of AC, no closets/drawers at all, ...Consider this hotel only if you canwt afford to sleep on the island.

Hôtel très bien situé sur le bord de la mer

L'hôtel est merveilleusement bien situé sur la belle plage de Shibukawa sur la mer de Seto. L'hôtel nécessite cependant de sérieuses rénovations. Les tapis des corridors sont sales et tâchés, les murs sont grafignés. Les chambres sont dans un état usé, les matelas sont très mous et usés. Il y a cependant un grand balcon qui aurait aussi besoin de peinture et aussi de chaise pour profiter de la belle vue qui nous est offert. Un hôtel qui pourrait être un WOW après d'importantes rénovations. Pour l'endroit : 8/10 Pour la nourriture servie: 8/10 Pour l'hôtel: 5/10 Pour la chambre: 4/10
