Sincere staff & fantastic sea view.

The reception staff was very friendly and helpful, especially the gentleman who tended to us last night. He was very patient and especially helpful to our multiple queries and tried his best to help. We were very grateful for his sincerity in wanting to help. Recommended us to a wonderful place for dinner too which we enjoyed tremendously. The view from our room is fantastic! Thank you for everything!

大きな窓に海の景色で最高のロケーション

低価格で海沿いでWi-Fiのある宿泊設備を探しており、今回滞在させていただきました。Wi-Fiは弱めですが価格がお手頃なのでOKかなという感じです。プチワーケーションで利用しましたが、大きな窓と波の音でロケーションが最高でした。欲を言えば、しっかりしたWi-Fiと机と椅子があれば、ワーケーションでもっと利用しやすいと思いました。淡路島は大好きな場所なので、また機会があれば利用したいと思います。

安く宿泊できて部屋も人数少なかったのでゆったり使えました。 大浴場の窓に目隠しが貼ってあり全然海が見えないのが残念でした。中からは見えるタイプのシールだと良かったのですが。

一晩中、朝9時まで入浴が出来て、 喜んで朝風呂に入りましたが ぬるい！というか、水？ 急に寒くなった時でしたが、 寒くて、上がれませんでした。 最大で熱い湯を入れ、ひたすらにかき混ぜましたが、 全く温まることなく、 しかたなく出ましたが、 風邪をひきました。 混ぜいた腕もパンパン エレベーターがないのも、ビックリ ゆったりフロントでおしゃべりされてたから、荷物運んでくだされば、嬉しかったです でも、スタッフさんの笑顔は素敵でした。
