ラドン温泉が魅力の宿。 岩盤浴も男女共用のものとそれぞれの浴場にあるスチームタイプとあり、１泊では勿体無かったかなと思います。 部屋は広々としたツインの洋室。とても清潔感があり寛げました。室内にお風呂は無いが温泉が充実しているので問題ありません。 食事は2食とも味、量ともに満足でした。 シルバーウィークのため料金は高めに感じましたが、普段の時にまた行きたくなるお宿です。

ゆっくりと過ごせて良かったです。岩盤浴と温泉を存分に楽しみました。 スタッフさん達の対応も良いので安心して過ごせました。 ここにお世話になるのは三度目ですが、食事の味が落ちたように感じました。 そこだけが残念です。 次回は夕食は予約に入れず、定食をいただきたいと思います。

他の旅館やホテルと比べると設備などは劣るかもしれないが、温泉付属の宿泊施設と考えると満点。 伊豆長岡の市街地で、伊豆のどこにでもアクセスしやすいことを考えると総合的に良い。

Wonderful hotel within about a 10-15 minute walking distance from Izunokuni station. Also a short bus ride away if it's too hot. The rooms are spacious and beautiful. Amenities include public bath, and even two massage chairs you can use for free! Staff is also very helpful with your questions. One inconvenient thing is the hotel restaurant takes last order at 8:30 pm, which is really early.

レトロな感じの旅館で、従業員のみなさまにとても暖かく迎えていただいた。温泉も質が良く、岩盤浴も希少な北投石を使用しており、ここでしか体験できないと感じた。ありがとうございました。

傳統的溫泉旅館，但房間裝飾是新，很乾淨。一進酒店要脫鞋鎖起。職員不太會英文，但有軟件幫助；很努力盡責地解釋酒店設施。房間在2樓要走樓梯的。很好的體驗。
