Yeah that sounds about right, my air conditioner broke a ridiculous number of times and the heater didn't work at all. I didn't care about the heater cause I just used my electric ones anyway. It took them 3 weeks to replace my dishwasher...
I was in 2246. Oh and I'm getting ready to sue them because they're trying to get 2 months rent out of me because I left when my lease was over! They're saying I didn't give 2 months notice....why would I give 2 months notice when I left when my lease ended...
Landmark Properties is the owner of all that, you may want to complain directly to them...also go on apartment hunting sites and bash them, trust me they'll fix your crap ASAP after that.
