"Sehr gutes Hotel für zwei Nächte Nagano."

9.0

Guter Service durch den Shuttlebus vom Bahnhof zum Hotel. Freundlich vom Fahrer bis hin zur Rezeption. Wenn man den Weg mal erkundet hat, kommt man vernünftig zu Fuß in die (überschaubare) Innenstadt. Geräumiges, komfortables Zimmer.

In direkter Umgebung leider kaum Geschäfte und Restaurants (außer hoteleigenes).
