Hi Robin, My ferrets have their own medium sized bedroom that has a 6'x 6' skylight and no other windows. Its main drawback is that the ferrets can't see what's going on in the rest of the house. They really like to be included in whatever is going on. So whenever I'm home, I almost always let them out to "help." One thing I like about this room that a closet might not have, is a good source of natural light and some fresh air (it doesn't get too cold here in the San Francisco Bay Area even though I don't directly heat my house). I don't know if it's coincidence, but all my guys except the one who had surgery this autumn have really thick, silky winter coats. If I didn't have this room, I'd probably just keep their big two story cage in the corner of the living room. I also wouldn't keep ferrets in a non-walkin closet. I think it would be too dark, small, and boring for them. Maybe the person who suggested not keeping them in a closet thought that's what you had instead of a walk in.
