モダンで清潔なホテルでしたが、駅からのアクセスが不便でした。夜になるとホテルの周りは暗くて歩ける感じではないです。コンビニもレストランもありません。車利用ならば問題は、ないと思います。

Love the services of the staff. They are perfect and very helpful. The villa space is good but the amenities are slightly aged. The villa filled with musky smell due to all the wood furniture. Other than that, the villa is very clean, the bed is good and clean. Last shoutout to all the staff, well done!
