It's really decent place if you're unwilling to cost a lot on accommodation. The biggest drawback might go to the inconvenience to the train station cuz you have to walk for 20 minutes to reach the hostel (but there's local buses if you find walking too tiring and sweaty.)
Overall it's better than expected and the staff are really nice and sincere to answer any questions. The facilities are well-equipped, including the kitchen, dining area and entertaining area. Btw, some rooms even command a fantastic panorama of Mt. Fuji, which really stuns us when having spotted its greatness.
Thanks again and highly recommend for those who consider living in Fujikawaguchiko.
