Lol dude who says that the commute to Manayunk is 15 min... Actually a philly resident here, have been living and working in south philly for like two years so i will give u the actual lowdown of whats going to happen if u move to Manayunk. You would have to drive to the train station every day from your house, you would then need to pay for parking for your car at the train station while its there, wait about 10-15 min for the train to arrive, realistically looking at a 20-25 min commute by train during rush hours when everyone is going to work (probably coincides with the time you need to be at class). Once u get off the train station u def need to transfer to a subway station to get to temple which will take another 10-15 min. Grand total of anywhere from a 40-1hr commute every day. you also have to get a septa pass since every transfer requires a septa token. This would be every day...
Theres plenty of affordable places under 900$ as long as u room with at least one other person in center city. Currently im living in a place with a roomate in Center city for 825/month with a roofdeck, basement and w/d in unit. Dont treck all the way out to Manayunk, as a philly resident this sounds like a bad idea and i would highly not recommend it. Theres tons of places near the BSL, i mean its only the longest subway line in philly and the subway is super fast!! Just my opinion but if you want to move here and find out for yourself be my guest.
