absolut recommandation: Really nice little apartment, perfect size for one traveller in my opinion. It's less than 1 Min. from the station and the neighborhood is very nice with ramen shop, Izakayas, supermarket etc. The alarm code system works very well once you figure it out and the advantage is you never have to worry about losing or forgetting the keys.
Only thing to be aware of: carrying a big suitcase up the narrow stairway is …a challenge. But you only have to do that twice ;-)
