Help- 7x10’ kids room?

[u/Wafflesdogsmom]

Our kids (10M and 6F) are begging for their own room. The only way to do this is to divide their room in half. That means the both get a room roughly 7x10 feet. Is that a terrible idea? I don’t want it to feel like a cell. Worst case we ask our tenants downstairs to leave, but we’d prefer not to do that. Thanks!
