When you quit the lease, you need to basically restore the apartment to the way you checked in, that is, clean the apartment, leave no personal items or garbage, and keep all the facilities in the apartment intact. You need to fill out the Move-out checklist, and check with the apartment staff one by one whether the required cleaning is up to standard to ensure that the deposit can be fully refunded. Don't forget to leave the correct check payable and mailing address to the apartment.
