ʿAmr ibn Shuʿayb reported on his father’s authority that his grandfather (May Allah be pleased with him) said: Messenger of Allah (peace be upon him) said, “Command your children to perform Salat (prayer) when they are seven years old, and beat them for (not offering) it when they are ten, and do not let (boys and girls) sleep together”

Scholars maintained that prohibition mentioned in this hadith refers to the forbiddance of sleeping at the same bed. There is no problem of staying at the same room as long as no ʿawrah is exposed or any problem may occur.

Almighty Allah knows best.
