It's a big room, so we could put a mattress (or two) on the floor for people passing through.
However as Gwilym grew bigger so his room seemed to grow smaller and smaller.
So we have swapped rooms. It means I get a nice sunny office, but sadly it's too small to have people sleep on the floor, with or without mattress.
Gwilym gets a nice big room, but alas, it's too full for folk to sleep on the floor unless they are OK about sharing the bunk with Gwilym.
Oh well, you win some and you lose some.
