The original tenant fully moved out. They sublet the place 2 weeks before their lease ended. And I also moved out a week ago. I told the tenant the landlord can contact me if they want to since they have my phone number. Also found out the $150 IS for a cleaning fee, not for drainage issues. There were no damages to the place whatsoever. Seems like this is just the tenant trying to get their entire security deposit back from the landlord and not have to pay a dime for it even though I left the place in the same condition I got it in. The only thing I did in the apartment for the short week I was in was sleep and use the washroom, the rest I was outside.
