If you live with roommates and are close to your roommates, like if they're family that could be an option, if not I would just section off a little part of the closet or corner in the rooms u do have. It doesn't have to be big at all just a space to sit, an available option for the kid to have their private space. You can literally use those rectangular plastic laundry baskets and put a pillow in there, my son did this to make his own makeshift space in my parents room one night when he got upset and didn't want to go downstairs to his calming corner lol! U can also use one of those teepees or mini kid pop up tents if u can't or don't want to take up permanent space anywhere...
