If you live in an apartment and you rent, it is the landlord's responsibility to get it fixed, isn't it?
I've rented before and I've rented property out too! Usually in the rental contract, the renter is responsible for small maintenance jobs, like fixing a faucet- I say usually but not always! That was a point in my rental contracts! No way was I going to run over to my rental property at 3 in the morning to make minor fixes!
