Like the other reviews say, this is a very rustic but charming place. Unfortunately we went when it was a bit cold (11 degrees) and we tried the stove (wood heater), which caused us to leave a night early.
The stove is setup so that the smoke from the wood burning comes back into the room, making it completely unsafe and uncomfortable. We bought a heater for one night and left the next.
The chimney is just a horizontal pipe outside the house. It should be vertical with something on top to protect from wind blowing the smoke into the house. As a result the smoke goes out but every few minutes the smoke would blow inside as it changed outside. We had to open all the windows and door to breathe.
It is definitely unfit to be used in cold weather at the moment. The chimney needs repairing.
We were also told it would cost extra to use wood and were lectured for 20 minutes about it being the wrong season to use the heater/stove. It was a rather tedious, long drawn out check in process. Mona was nice but lingered too long.
It was also awkward being told to meet on the stairs where everyone takes photos - people kept asking us to move. You just need to go up to the top of the coloured stairs and turn left to get to the house. Then you will recognise it from the photos.
Maybe the chimney will be fixed, but if I were you I would check before booking, otherwise winter will be either freezing cold, or like having a bonfire in the actual room with all the smoke.
