My oldest son, age 21 moved out and left a spare room:-)
Placed next to my old bedroom in the basement. It's a good room to sleep in, while it's dark and newer to hot:-)
Notice that extra person no. 3 have to sleep on a matress on the floor, or in a camping bed.
We have what you need to sleep, sheds etc. For the beds, sheets are to be found in the wooden box with grey top in the room outside your room, where we dry washed clothes on strings.
Covers for pillows and blankets are on the little, narrow shelf outside the rooms. I expect you to be able to make your own beds ready to sleep in.
Clean towels are in the room, and you can use the washing machine.
We vacuum before you arrive but don't expect extreme clean facilities:-) It's an old house and it is our basement but I also have had my bedroom there and I like the darkness and the nice sleeping temperature during the hot summer, and of cause we can heat it up as well in the winter.
We have several bikes, a wonderful garden and terraces, which you can use, during your stay.
