"旅の目的をホテルにしても良いくらい良かったです。"

Exceptional

10.0

シャトルバスもあり、荷物の上げ下ろしのサービスまでも行き届いていました。ホテル内でも、ホテルの方達の対応がとても丁寧で、私は12階に泊まりましたが、エレベーターから外を見る事も出来、部屋からの景色も最高でした。煙草の匂いが苦手ですが、ホテル内は常に快適で、清潔でした。朝食付きにしましたが、地元ならではの物が並び、飲み物も他ではなかなかないくらいに選ぶ事が出来ました。私はパンを選択しましたが、どれも美味しく、高級ホテル内で食事をしているように感じました。アメニティも揃っていて、香りもよく、浴槽も広くて文句なしのホテルでした。チェックアウトも１１時なので朝の準備をゆっくり出来たのも良かったです。

写真ほど広くはないとは思いましたが、それ以外には良くない事は何もありませんでした。

浴室へのドアの建て付けが悪く、なかなか閉まらない。絶対気付く欠陥なのに、一言も事前の説明なし。業者に頼めばすぐ直せそう。ま、良いんですけどね笑

The breakfast was wonderful- great variety. The location was a little out of the way. The onsen associated with the hotel was a very relaxing trip.
