Like Danked said... a hung ceiling is your enemy in this battle. Having drywall would cover the first floor joists of your landlord's house and would seal off much of the smoke from escaping into the cracks between the floorboards/ plywood. Hung ceiling is just 3/8" piece of foam, cork, or sound dampening gypsum in a grid, with plenty of crevices for the smoke to escape up to the joists. I'm guessing your apartment isn't in NYC, where tenencies are required to have one hour fire seperations between one another
