If your house was built in the '20s, likely there isn't much insulation in the roof/attic and you may not be able to just add some without rewiring, as it may still have knob and tube wiring. Most heat loss occurs through the ceiling/roof as heat rises and cold falls.
Windows are the next biggest loss, and to get you through this winter, you can go to the hardware store and buy a roll of plastic and tape it over the windows. You might even want to cover the trim too, as there often are weight pockets beside the windows that are only covered with trim on both sides. My windows weren't leaking themselves, but they had been installed so badly that the walls and trim around them were leaking like a sieve. We took the trim off and sprayed Great stuff all around the windows, then reinstalled the trim. That helped more than new windows would have. There are also special kits with heat shrink plastic that you can put over windows, but they don't usually cover the trim too.
The floor is also suspect in older homes, especially if heat is being lost through the attic. As the heat rises through the attic, it draws cold air from somewhere. In modern homes, there is a plywood subfloor. In older homes, there is often just barn boxing laid on a bias, then flooring laid perpendicular to the floor joists. Cold air can be pulled straight up through the gaps in the floor to replace what is going out through the roof.
Also in older homes, particularly if they have been rentals, the utilities have been installed multiple times. The phone company and cable company, in their wisdom, rarely look for the hole where it was installed last time and use it again. They just drill another and another and another. Over time, this can amount to many holes in the rim joist, siding and floors. Great stuff or caulk or both can really help tighten that up.
Its too cold to caulk right now, it won't stick and it won't cure, but if we get some warm days, get outside and replace the caulk around your windows and doors. That will help a lot too.
Don't forget your chimneys. They are a big source of heat loss. Your heat rises right up the chimney and cold air comes right down it. Make sure your dampers are closed. If you aren't using the chimney and nothing is venting through it (like your furnace or hot water heater) you can always board over it. The last year we had I fireplace (before I tore it down), I stuffed the firebox full of 2" slabs of styrofoam and then bolted the doors closed so the wind couldn't pop them open. The thing was leaking badly, as it was built of interior grade bricks and water was getting into them and splitting them. It wasn't safe to use either, so I took it down the next summer, but the styrofoam got us through that winter without freezing. Just be careful to make sure nothing else is venting through it first, so you don't kill yourself with carbon monoxide poisoning.

No, the house belongs to my roommate: I'm not investing in money for her house. We'll only be here for two more months, but it's freezing, and we have babies. (Two of them are under 2) so I want a cheap way to cut some of the draft out. It's only the downstairs that has this problem, in the living room, but that's were we spend the day... so we have to get it fixed.

Maybe there is a warmer place you can spend the day with your children? The Public Library is a great place...some have movies and story time for children, plus it will be warm.
God bless you and Merry Christmas!
