This is basically the commodization of hotels at its finest. We had four of us staying in a hotel room meant for two at a reasonable price because we were only there for two nights. Some people might complain about the squishiness or the room missing some home comforts but it truly fitted purpose fine - you get what you pay for.
As noted, the hotel is incredibly convenient to the train station. Computerized check-in system, but the staff walked me through it by hand. They'd forgotten to set up the sofa bed in the first room they gave us, but when we bridged the language gap (I was asking for sheets for the sofa bed I'd then set up, which was the wrong question) they moved us into the same room with the bed already set up with sheets. They were very pleasant to deal with.
When looking for somewhere to stay without breaking the bank in Nagano, I would happily stay here again.
