i have lived at quail run for 2 years. i really have not had any major problems, just the normal ones. the only thing i would complain about is the stairs if you lived on the second floor, also the noise from the other neighbors.
i would however like it if there was more security, as in checkpoints or just some guard on duty at the entry points.
when i do have an issue i contact the front office and usually they take care of it promptly.
