I just wanted to say a big thank you to Mr. Koga. He accompanied us to the express bus stop, waited with us until we boarded and even translated to the driver to make sure we reached our destination to Rinku town station. He was so helpful our journey was so much smoother. I truly appreciate his help.

夜11時までと、朝7時から露天風呂に入れます。 朝食レストランは和食中心バイキングですが美味しく、海が見えるのが良い。 千畳敷まで近いので散歩に良さそうです。 今回はアドベンチャーワールド目的で宿泊しましたが、すぐ近くのバス停から行けます。 白浜駅から、夜タクシー利用で三千円程度でした。 この内容と料金は満足できました。
クロワッサンや、食パン、ドリンクバーもありました。

温泉がわりと広くて、貸し切り状態で、ゆっくり入れて、とても良かったです。静かで、部屋も広めでした。少し古いので、とても綺麗な部屋とは言えませんが、普通に清潔でした。 朝食バイキングも付いてて、そこからの海の景色が綺麗です。平日だったこと、海水浴シーズンでなかったこともあると思いますが、コスパ良かったです。
