I had this in rented accommodation, I didn’t like it at all, firstly the noise , particularly if someone wanted to sleep, lie in, early night, a nap, as it was close to bedrooms, even just getting ready, you could hear it.
Also it’s a proper ballache taking wet laundry downstairs,to hang out. It’s just as much as a ballache to take upstairs to be fair. But it feels extra to take it down, hang it out and then take it back up again to put away, the other way round irs already up there when dry so less work.
I also had two places where it was in the loo. The first was rented. I like a nice bathroom, it’s not nice with your washing machine in there. Even when in a cupboard, the second I owned and I had it moved out. Something about shitting next to clean laundry which turns my stomach.
for me the ideal is a downstairs utility with room for an airer and access to the garden, if not then in the kitchen.
