We stayed at the Chisun Grand Nagano for 4 nights- triple room share. Although it was a squeeze for three pax, the hotel made up in terms of cleanliness, provision of amenities, and friendly, helpful staff. There is a self service amenities bar at the lobby which we made use of. The hotel also loans items like umbrella, cutlery, iron etc. The room was clean with no funny smell. Location was also great, five minute walk from Nagano station.
