Upper floor: living room (there is an awful smell of gas), kitchen, bathroom.
Lower floor: bedroom and a seperate toilet.
You need to go outside from the lower to the upper floor.
We stayed here in december and it was very cold inside the house. We've used the wood stove (wood we had to buy), otherwise it was too cold in the living room.
I told them about the smell of gas (they told me it is not dangerous) and they told me, someone is going to contact me - nobody contacted me.
