We booked this place since it is located in a remote area, away from light pollution. We saw aurora borealis both nights, and it was great. :)
Just to set your expectations - the hotel is basically more like a farm, with the central building where you have common facilities (the free coffee is great) and then there are barracks around it - our room was in one of those.
We got into the room with the code the hotel sent us - you should type it on a keypad which is on the door handle. Very convenient! The room was small but nice & clean. Very important to mention is that there is little to none isolation, so although the heating was on maximum, the room was so cold we slept fully dressed. The next day we accidentally found an additional small electric heater somewhere outside, so we brought that in. Ideally I'd imagine that someone would check the temperature when they set up the room and get that heater preventively in.
