More on transit:

Your nearest bus route is the 2, which runs north on 16th & south on 17th. That'll take you down into the Rittenhouse area or beyond if you prefer not to ride the BSL.

The 33, which runs inbound on 19th, is one of those super-handy L-shaped lines - it goes down to Market, then turns East and runs all the way to Penns Landing. Coming back it goes west on Market & JFK, then north up 20th.
