"The hotel is very close to the Shizutsu Station. It is five minutes away. The room is clean and tidy. The Japanese-style breakfast is very rich. There is also a large supermarket, Xinglin Hall, a variety of cosmeceutical food and daily necessities, all of which are inexpensive and small. The town is also beautiful and quiet. When we left, we took the suitcase and went to the station with the rain. The tall guy at the front desk chased out and sent us three umbrellas. It was so warm."

"Before going, I didn't expect it at all because it was too cheap to stay overnight. I thought it would be good to stretch my legs and sleep, but it was very clean and the tatami mats smelled comfortable, and it can be recommended for women"
