When booking our reservation, there were definitely a few potentially concerning reviews, but frankly I have to wonder if those people understood they were booking at a hostel. The overall experience was quite good -- my partner and I stayed in one of the private rooms and while it was a nice stay. Bed was quality, good black-out blinds for the windows. Heater was very effective. Helpful friendly staff.
Objectively, the fact that you have to go outside and walk a bit to access the bathroom and the bathroom needs a keycode to enter becomes a bit annoying, but you do not need your phone to enter the bathroom as one reviewer seemed to think.
