Camden, like many large apartment firms, uses a computer algorithm to assist in setting rents. I mention this because rent for similar Camden Copper Square apartments can vary by a couple of hundred dollars month to month, dependent on nearby vacancies... So, if you price Camden and it seems a bit expensive, check back in a few days or weeks or months, particularly if you are searching at peak seasonal moving times. This can impact you when your lease comes up for renewal as well. It's a bit of a gamble, but being patient and watching rates can often save you a significant amount. Also be aware there are some fees (garbage), which are really just an indirect way of charging you higher rent. They need to be considered when you are budgeting.
I was about to assign Camden Copper Square a three star rating and my daughter, a resident (two years) at Camden until just recently, insisted that I bump it up to four stars. "I really liked the layout of my apartment and the staff there was quick to make repairs... And there were no unexpected charges when I moved out." I'd also note it's very conveniently located near Chase Field, the Arizona Science Center, the U of A Medical School, ASU nursing... The parking garage is safe and convenient, the swimming pools and exercise facilities are resort-like and there is a nice little dog park.
Concerns? It's not a great neighborhood to the East and even a walk to the West often involves stepping around homeless souls at the bus stop. In addition, if you're a young professional or a graduate student, the influx of ASU undergraduate students is a bit of an issue (avoid apartments near the main pool). The growth of ASU downtown has changed the character of many downtown apartment complexes as students, often motivated by the "dry" policy at official ASU campus housing, move off campus. But there are clusters of young professionals, medical students... at Camden Copper Square, which is worth inquiring about if you are concerned about noise. Much of the northwest corner of the complex, around the small pool, is one such area as of this writing.
One more practical suggestion. Since there are no elevators, consider renting a truck from Home Depot if you are moving yourself. Unlike a UHaul, these trucks have low enough clearance to fit into the multi-level parking garage.
