As I communicated with Emilia, the toilet was clogged the first time for normal usage. I don't think we are resposible for this kind of maintenance. there was ice all over the road and in front of the apartment. it took us quite some time to find the apartment driving on the scarily hazardous road. Several people fell in front of the apartment. Since it was Christmas eve, we didn't bother to complain about the accidents on ice, or the clogged tolilet, trying to give landlord as much as peace as possible. We went out to get melting salt on our own. We only reported clogged toilet the second morning. We washed dishes and dumped garbage one night before leaving. We did our best to clean up the aparment, although you charge us cleaning fee. The door is locked automatically every time we went out. I don't understand why you said it was not locked. Do you complain just because we don't agree to pay for the clogged toilet?
