Put them where ever the dust will be least difficult to clean up. You may find that they are far more messy than you ever thought they could be. Many people, after brooding chicks, say... Never again in the house. I allow my chicks to be in the house for a couple of days, then kick them down to the garage. As long as you have a draft free predator proof place for them, and can keep the temp high enough with a brood lamp, it doesn't matter where they are. The bigger you can make your brooder, the better it will be for the chicks. They should have enough room in the brooder so they can get away from the light to a temp that is around 70 degrees or less. If you don't use the upstairs bathroom, you could set your tote in the bath tub. If this room has a window, that would be my first choice. Under no circumstances would I brood chicks in my kitchen. Enjoy your little fluff balls.
