"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"

"The location is good with a big car park. Although the staff cannot speak fluent English, they tried to explain all the details during check in. There are not many restaurants nearby but you can find 1-2 24 hours fast food restaurants beside the hotel. Not really a lake view as mentioned by the hotel description though. Not far away from the lake and the lake is big and beautiful."

"The location was very good with Lake Hamana from the window in front of the station. Breakfast was also delicious with a lot of items than expected. Because I stayed on Sunday, it was a pity that all the few night rice restaurants were on regular holidays."

"Very close to Xinsuoyuan Station, about two minutes walk. However, the adjacent Tokaido main line runs all day, and the frequency of the freight train at night is not low. Even if the guest room has a better sound insulation device, there is still noise vibration on the top floor at night, and sensitive people may be difficult to sleep. In addition, the boss has more ideas in hotel management, you can go to the hunt to try it~"
