We have lots of rooms full of junk..... including the spare room (no room for guests at the moment!), the study/sewing room, the garage and a self-storage unit.... we are planning to move to a bigger house soon!
yes the spare room has a single bed rolltop desk
which I never use it just stores things sewing machine chest drawers bedside table, chair etc
grandson when he stays refuses to sleep in this room he says too much old stuff.
In my current life, had to downsize from high-set home with area 29 squares up, & the same, down.
But house now approx FIVE times smaller in area, so every room is a spare room, with cartons' as this house has NO CUPBOARDS!
AND furniture & my 'stuff' in 6m x 3m storage unit!
