My first year there was great, but then a lot happened in my last few months: Dishwasher broke (fixed promptly); AC broke (fixed after 2 days of me calling and saying it was 86 degrees in the apartment); pipe burst in my bathroom (water stopped immediately by maintenance but then it took four days to fix my carpet during which time I had to find another place to stay); and garbage disposal leaked (fixed promptly). I also had two packages stolen in that time and saw more cockroaches and millipedes in my apartment and hallway than usual.
One day I came home to an eviction notice on my door saying I had to vacate in three days because of failure to pay rent. This especially upset me because I had noticed that my rent never debited from my account and had contacted the leasing three times about it, each time hearing, "Sometimes it takes up to a week." That got smoothed over a few days later.
My last invoice after moving out contained charges that I'd been told would be waived - like carpet cleaning because they had to replace all of my carpet anyway - and I had to argue with them to take them off.
Little annoying things: They make a big deal about all cars in the parking lot needing to be in great shape (no dents or rust, etc.), but in the small section where I always parked there were two vehicles that had not moved in so long that the tires had gone flat and dust had settled over them. Also the entire time I lived there, my screen door to the balcony never opened or closed without coming out of the track.
