You'll need to swap position of a storage cabinet ( a very Small wardrobe 2 doors) with a chest of drawers inside the bedroom. You don't have to move the furniture between floors, just change position in the same room
this needs to be transported. i am able to help on both sides and there is someone on the other side that can help also. there is a lift on my side but it might not fit in the lift but the stairwell is big and plenty of space to bring it down
