Read more 早目の到着にも気持ち良く対応していただき本当にありがとうございました。 チェックイン前に周辺のスポットを色々教えていただき温泉に入れるようにタオルも用意してもらい到着早々観光を楽しめました。 チェックイン後も丁寧で笑顔の対応心地好かったです。 喫煙のお部屋でしたが空気清浄機もあり煙草臭さは気になりませんでした。 お部屋の古さはありましたが掃除も行き届いて良かったです。 温泉はとても気持ち良かったです。 立地で選んだ一井さんでしたが間違いなかったと思わせてくれました。 お世話になり本当にありがとうございました。

Thank you very much for the early arrival. Prior to check-in, I was able to enjoy various sightseeing spots as soon as I arrived and taught me various spots in the surrounding area. Even after check-in, it was polite and the smile was comfortable. Although it was a smoking room, there was an air cleaner and the cigarette smell was not worrisome. There was oldness of room, but cleaning was good, and it was good. The hot spring was very pleasant. It was Mr. Ichii who chose at the location but made me think that there was no mistake. Thank you very much for your help.
