Not long and we will add a washing machine to the luxury of our guests. A second hand one and it will be in a space next door to the unit. The dryer will be next, so for the time being it is only for long term guests that can dry their clothes in one extra day.
The nearest laundrette is 20 km away and not practical if you have little time left. Most people bring small amounts of clothing when tramping and then they are so relieved when they find an address with a washing machine! Can't wait to offer it.
Since I don't want to be asked if they can use my private washing machine. There is always stacks of washing to do on the farm anyway let alone all the sheets from the guests!
