YES! and for free...

If you live with other roommates, you are insured under the "Occupant's Civil Liability" cover, which applies to the tenants declared on the lease of the insured accommodation.

If you live with four flatmates in a superb apartment, make sure you declare them as "Other inhabitants of the dwelling" by filling in their names when you take out the policy.  

Reminder : only the roommates mentioned on the lease are covered by the insurance contract.
