8/10 Very Good! (495 reviews)
Overall it is really an excellent hotel. Many of the rooms should be updated, but still they are adequate and spacious. The breakfast area can be busy, but there is a large adjacent room with plenty of space. The hotel staff were great. The onsen has a spacious indoor bath and plenty of washing areas. The outdoor bath is very pleasant, just be careful walking on the stone surfaces. The staff takes good care of the onsen and sauna. The location is good. You can walk to Nagahama JR station and the old town area is just beyond. The lake and the large beautiful next door park and castle is good for walking. There are not many restaurants open at night in central Nagahama, but you can probably find something.
