Bed bug free hostels in Nagano, Japan

How this list is filtered

This page excludes hostels with bed-bug reports across the platforms we read, including Hostelworld, Booking.com, and Google Maps. Any active pattern, or even a few recent reports, removes a hostel.

The bed-bug detector runs on the Punk AI Language Model, which is not very large and runs locally on a cheap laptop in a hostel. Suspicious-review flags still appear when review analysis finds signs of bought or incentivized praise.
