Good 4* hotel in between the main tourist areas - the station / shops and Zenko-ji temple complex. Nagano is not a large city, so perfectly walkable from either location.
The hotel itself was fine - staff were welcoming, and happy to converse in either Japanese or English, and check-in / out was efficient and hassle-free.
I would definitely recommend staying in the tower wing rather than the regular one by the way, it's newer and better decorated.
The only mild issue was that they only had two single beds available rather than one queensize, but that was more down to it being a busy season for nagano rather than anything the hotel did wrong!
Anyway, would be happy to stay there again if revisiting Nagano.
