I holiday in other peoples rented cottages a lot. If my husband and I go alone (grown up kids) we would never dream of using a washing machine. However when we used to have the kids with us it was a really useful feature.
We've got an odd shaped kitchen at our house and I found the 'advanced search' on the comet.co.uk website a good way of searching for fridges by size and they're good value

Good luck!
