全体的には満足でした(^｡^)
スタッフの方2人ともとても親切で穏やかで、色々と質問しやすかったです。唐津城近くリバーサイドでロケーション⭕️ウェルカムドリンクにアルコールもセレクトの中にあり、飲む家族は喜び⭕️その他ソフトドリンク22時まで自由に飲める⭕️
ただ、お風呂が家族風呂で時間が予約で限られていたので、温泉にでかけました、それかちょっと残念だったのと、エレベーターが無いので足の悪い人やお年寄りは厳しいかなと思いました
エレベーター、大浴場が無い

お得感満載
2階の角部屋ということもあり、川や川沿いの景色はもちろん綺麗で唐津城が見れたことが素晴らしかったです。
檜風呂の1時間貸切りもお得感満載だったし、22時までのウエルカムドリンクサービスも嬉しかったです。
朝食は川を正面に眺めながらの食事ができる配置をしてくださった心配りのおかげで、さらに美味しくいただけました。
2日間を通しての対応が、とても素晴らしくて快適でした。
