夕食のお料理がかなり薄味でした 朝食のカレーは甘口でしたが美味しかったです。 お風呂は表示より少しぬるい気がしました。 長く浸かるのが目的なのかな？ 日帰りで入浴されている方がかなりいらっしゃるようです。大きくタトューが入っている方もいらっしゃいました。お子さんもはいるのて、そこは強く明示してくれると助かります。

温泉施設がいくつもあり、良かった。 特に温度の違う湯船が良かった。 また大浴場の他に貸切露天風呂や、有料貸切風呂もあり、次回はそちらも楽しみたいと思いました。連泊したので、料理は初日の方が良かった様に感じました。品数は多いですがもう少し工夫が欲しい様な。後朝食は洋食も欲しかったですね。

掛け流しの温泉、私の身体にとても合う温泉だった。 また、従業員の手作りの、朝焼けの富士山と、ダイヤモンドご来光が独り占めできる、貸し切り露天風呂。 　好みの浴衣を着て、一日に何度も温泉へ入り、すべてのストレスを洗い流せる。 　 　建物は、昭和時代のまま。 昭和のひとには懐かしくて、帰る頃には令和の行き過ぎた便利さを残念に思うようになっていた。 　とても貴重なお宿だった。

昔ながらの旅館で居心地も良く、富士山の見える貸切りの温泉も楽しめました。 チェックアウト時こちら側でトラブルがあったのことにも快く対応して頂き、大変助かりました。ありがとうございます。 また遊びに来た際は、利用させてもらいます。 This is comfy and traditional inn. We enjoyed Onsen with My.Fuji view. I really appreciate for kind staff took care of the problem when we checked out.

設備は古く、ビジネスツインには鏡や洗面所・トイレがありませんでした。しかし、大浴場のすぐ前なのでそこを代わりに使うことができます。 値段がお安いのでこれでもいいかと思いました。 事前支払いの金額を見ると、税金が割と高めに設定されているように感じるのですが、どういう明細なのでしょうか。それとは別にチェックアウトの時に、入湯税を150円現金で支払う必要がありました。
