* Koshuis kamer: This is probably the closest and most common translation. "Koshuis" means "dorm" or "residence hall," and "kamer" means "room."
* Slaapsaal kamer: This translates to "dormitory room." "Slaapsaal" is a more formal word for dormitory.
The choice between these depends on the level of formality. "Koshuis kamer" is generally preferred and understood.
