I'm working on a setting for a tabletop RPG game. This place is located high on the mountains and it is cold. There is a village in this place and their is and inn who's only room is on the basement of a hut (the hut is something like this https://en.wikipedia.org/wiki/Cloch%C3%A1n).
Given that there is a basement dug under the hut what would the temperature be of that hole? Would it be the same temperature as it is outside or would it be warmer? If it is warmer and given that the temperature outside can be around 35 to 44 degrees Fahrenheit (1 to 7 Celcius), would it be warm enough that you wouldn't need to use warm clothes there?
