Rents are very reasonable, and you can't beat a neighborhood that's home to the Pleasure Bar and the Bloomfield Bridge Tavern. East Liberty is northeast of Bloomfield, next to Highland Park. Housing here varies.
Bus service is good, rents generally cheap.
Friendship is tucked in between Bloomfield and Shadyside. Greenfield is sort of a suburb of Squirrel Hill. Located on the southeast side of Schenley Park from Oakland, Greenfield is primarily family homes. If you can find an apartment or house for rent here, though, you can get an excellent deal. The neighborhood is safe and family-oriented.
