I have lived in the Commons for about a year and a half now since moving back to the 'Burgh from Cleveland. In a word- LOCATION. I love where we live... so easy to get to anything (much of which can be done walking), as a resident we do have parking (although it can be a problem because of NON Residents trying to sneak free parking in here), it is generally quiet despite the location (especially being on a higher floor with no residents above us), and the new office staff seems much more attentive and great than what had existed upon me moving in here. No place is perfect I have realized after living in various cities and having rented (and owned) in the past... overall my experience here could definitely be WAYYYYYY worse.
Pet friendly (unlike many places), attentive maint. team, package service at the office, workout room, rentable clubhouse/party room, etc... I like where we live and will stay here for awhile as long as it remains as it is :)
