Question: So I still have not found a place to live! I want to know where is the safest and/or best place to live?
In Philly, the right answer to your question depends on your personality and your expected standard of living.
If you're under 25 and it's important that you're near the "it" spots on the weekend, then look to Center City / Rittenhouse Square. You may end up paying through the nose--minimum $650 for a studio.
If you want a neighborhoodly feel but some distance from the "city" city, then consider portions of East Falls, Manayunk, Mt. Airy, maybe even Roxborough.
If you're a soldier, you can live near campus very cheap.
I though, would recommend South Philly east of Broad St but within walking distance of Broad. South of Washington, you can find 1 beds for $500/month and 2 beds for $750/800. These neighborhoods are mixed -- lots of diff folks, many Vietnamese and Mexican immigrants. Most blocks are very safe, if a little grungy. But, you're right next to the Subway, which'll get you to Temple in 15 mins and Center City in 5 mins.
I'm moving to South Philly shortly, before start of 2L. My future roomate and I are looking in this area and have been happy with our search so fare. In fact, there's a great 4 bed--newly redone w/ hardwood floors, new baths, and new kitchen for $1200 that we really like. Any interest in being the thris for $400/mth out there? IM if so.
