Only the tenants named in the contract are allowed to live in the apartment. If the landlord discovers that other people are living there, they may increase the rent or terminate the agreement.

You may not sublet the apartment, or any part of it, to another person without the landlord’s prior written consent.

You must also inform the landlord about any person who is not listed in the agreement and stays in the apartment for more than 24 hours or uses it for overnight stays.

You are.

The tenant who signed the contract is fully responsible for:

• the behavior of guests and visitors,

• any damage or disturbance caused by them,

• any fines, cleaning, or repair costs.

This includes problems caused by friends, classmates, or visitors you barely know. If they are in the apartment as your guests, you carry the responsibility.

Overnight guests are very limited:

• The Tenancy Agreement requires you to inform the landlord about anyone who stays longer than 24 hours or uses the property for overnight stays.
• Repeated or frequent, unreported overnight guests can be treated as unauthorized occupants and a breach of contract.

And remember: an overnight stay after a loud party is still part of the same problem – if there was a party or disturbance, it is already a violation.
