So the main reason why we booked this hotel was because it had hot springs! The hot springs were amazing (the hotel even provided yukatas for us to wear to it) and it certainly was an experience! (Considering none of us had ever been to a public bath/hot springs...)
As for the room, we learned that the "living room" area was also our "bedroom" area in that, in the evening, the hotel staff would move the table and seats off to the side and lay out bedding for us. Then, sometime in the morning, the staff would put the bedding away and move the table and seats back. Also, having an air conditioner in the living room was great because of the high humidity during the summer.
The hotel also provided breakfast, had a small shop, a tea house, and two restaurants on-site (a ramen shop and a full restaurant we never tried out) as well. We also noticed that they had an arcade (as seen in Expedia's pictures) and found that it wasn't as nice as the (single) picture showed. It was still a decent arcade but it didn't help that there wasn't a change dispenser.
One thing to note though is that the hotel is located far from the station, but you can take either the hotel shuttle (to and from the station during certain hours), the local bus line, or a taxi. We missed the shuttle a couple of times and ended up taking the bus, but only once did it take us to the hotel's bus stop. For the other times, we had to walk from the next closest stop, which took us a couple of minutes.
