快適なホテルで美味しい食事とリバービュー!

スタッフさんの対応も良く、ホテルは質素ながらも清潔、食事も素材の味を楽しめ、多彩なメニューに大満足でした。ロケーションも良く初めて川と海が交わるところをみました。川辺を散歩、近くのお寺も参拝できました。川の風は気持ちよかったです。 ロビーがおしゃれで ウェルカムドリンクバーでまったりできました。 またぜひ行きたいと思えたホテルです。

親子花火を用意してくださり、 大変楽しかったのですが、 子供が蜂のような虫に顔を刺されてしまいました。 途中で花火を切り上げ、 痛みが落ち着くまでお風呂にいけず。 幸い腫れずに翌日には痛みも和らいだのですが やはり自然のあるところは大変ですね。 虫対策をお願いしたいです。 あとエアコンの音が寝ている間 気になりました。 ブォォンと何度か部屋の温度調整?をしているのかな?でも快適なエアコンでした。 出入り口の灯りもセンサー?なのかな? 扱いがわからず 誰かが寝返りとかして 動くたびにカチッとライトがついて、 しばらくすると消えて、 また動くとカチッとついてと 一晩中ついたり消えたりでした。 あとこれはブッキングドットコムさんにですが、 こちらから予約すると 宿泊者情報がホテルにいかないらしく、 受付のさい 宿泊者情報を紙に記入する一手間がありました。

食事美味しかったです

初めから布団が敷いてあったのがビックリしました。 トイレの換気扇の掃除がしてないせいか、ハネの音がうるさかった

部屋からの景観がよい。 夜の食事が特によかった。同じような味付けのものがなかったのがよい。

チェックイン時点で部屋にふとんが敷かれていて、のんびりできない(事情は理解できるが…)次回はベッドにしようかと。露天風呂が殺風景。
