We stayed during the winter and we would say that it‘s not so much recommandable during this time of the year.
The room itself got pretty warm after putting on the heating but the hallway to walk to the toilet, which is also the entrance to the accommodation and their house entrance and the space you can sit outside your room was freezing cold, just like the toilet.
We also didnt know that the room does not have a window to the outside of the house, only a window that lead to the hallway.
Also the sleeping sofa was very uncomfortable to sleep on.
