Tiny bathroom, with a heated towel rail. Could possibly put some high level shelving but very limited in capacity.
We've got a reasonably sized terraced house but no airing cupboard. DH, who is usually much tidier and more orderly than me , seems to be happy with them just all being draped everywhere. We never know which are clean or dirty. There is space under the stairs (but obviously this is far from upstairs) or we could possibly do some sort of storage on the landing where the laundry baskets go.
We're actually moving back into the house after some time overseas in a house with 3 bathrooms and loads of storage, so I'm trying to think ahead on how we organise ourselves.
