"愛知県の自然に囲まれた素敵なお宿でした。愛知県在住ですが、なかなか県内旅行の機会はありませんでした。今回コロナで県外への行動制限により、このような発見ができてよかったです。古い建物ですので最新の設備ではありませんが、清潔で快適に過ごすことができました。(自然の中ですので虫は仕方がないと思います。) お食事も地産地消で楽しめました。忘れ物をしてしまいましたが、丁寧な梱包で迅速に対応して頂けました。"

"お風呂が心地よく、24時間使えるのもありがたかった。アメニティや飲み物等の備品が品質良く、使いやすかった。部屋にあるのでなく、フロント辺りに集約されているので、無駄がない。フロアにゴミの分別コーナーがあって、片付けやすかった。ゴミの片付けは自分たちでやって当たり前だし、部屋にゴミが残されずにいて良い。朝食のおにぎりが作りたてで、ほっこりして美味しかった！ 周囲の環境が静かで、のんびりと安らぐことができた。ありがとうございました😊"
