We had an excellent stay in Nanadaru Onsen. There are 5 different onsens, both indoor and outdoor onsen, which can be booked for private use. All are very nice. Dinner and breakfast had a wide variety and were very delicious.
Everything about this hotel is absolutely amazing from comfort, cleanliness, services to price and location. The cafe staffs are also friendly and dedicated during peak breakfast time. Overall, I had a very pleasant stay!
