Philadelphia

[nicky g]

Is Philadelphia a nice city to live in? My (American) wife seems to think it's pretty sketchy, but someone on the B&M forum mentioned in passing that it was mostly very safe, more so than most other big US cities. I ask because we will more than likely move over to the states at some point in the next few years and for variuous location-related reasons (AC [img]/images/graemlins/tongue.gif[/img]) it would be a good option for us. Is it expensive in property terms?
