It seems to me most of the responses on here are all horrible. Sometimes you hear noises but i have been in louder apartment buildings. I have called for maintenance. I believe that they have replied by order of urgency. when i had a water leak they were there within the hour when i had a small repair it took a day or two.
i have never had any other problems... but we pay our rent on time. if i can say one thing that does annoy me is some tennants drive quickly through the apartment complex and maybe should pay attention to the speed limit.
