食事は会場の雰囲気、内容、量、スタッフさんの対応、全てとても良かったです。お洒落な仕切りがちゃんと有って個室感ですが、隣の方の話がちょっと気になったかな。部屋も海や夕日も綺麗でGood ! 設備は嫌なほどではないが少し古さが。富士山が見にくいのは立地の関係で仕方ない感。

非常棒的海滨温泉度假酒店

位于户田御滨崎公园边上，面向骏河湾，海景及室内温泉都是一级棒，晚餐有当地特色的高足蟹，非常丰盛，因为是中国游客还专门给我找了会说中文的服务生，服务非常周到，可以帮忙预约租车等服务，还有专车负责到户田公交站的接送，总之住宿体验很棒。

夕日が部屋、風呂からみえる好立地

従業員の対応が事務的で優柔性がないと感じた。温泉はやはり源泉かけ流しがいいが立地と条件で難しいのかなと思う。
