Op it would be a hard no from me.
We stayed with ILs for about 6mths between houses. And DH was travelling for work. I with baby ended up travelling with him to get out the house.
Lots of tension, over cooking, shopping, noise, washing machine, dryer, putting my baby 70s style in the garden, we managed to be polite and avoid a full blown argument. But that is partly, we were in THEIR house not a shared house and were trying to 'keep the peace'.
I think it would have been full blown arguments if it had been a shared house.
Your children are preschool picture the scene Granny moaning about toys everywhere, then in 10 years time when you have tweens / teens playing on Fortnite, gibbering with pals, lots of noise. No you can't get a electric guitar to wake up Granny.
Or a bit beyond that 18 year olds going out and coming home at daft o'clock and Granny moaning because it wasn't like that in her day. Or them waking her up.
I know that seems a lifetime away but really it's only 15 years. Childhood is very short.
