How long would you share a bedroom with kids?

We are currently in a small 2bdrm apartment and our master bedroom is a storage room atm and we are rooming in the livingroom and my 2- 3y.os are sharing a room.

Kinda want to move us all in the master bedroom so we can have a livingroom 😩 obviously we wouldn't be intimate in the bedroom. I'd have to make their bedroom the storage room. The kids usually climb in our bed in the middle of the night anyways.. but curious how long room sharing is "acceptable".
