A more thorough explanation:

Definition: A place where travelers can stay overnight, like an inn or a household.

Examples:

• When we went on a road trip, we stayed at a hospitium in a small town.
• The hospitium was run by a friendly family who made us feel at home.

The examples show that hospitium is a place where travelers can stay for a night or more. It can be a commercial inn or a private household that welcomes guests. In both cases, the hospitium provides a temporary home away from home for travelers.
