I sure enjoyed 4 years in Squirrel Hill when I lived there. Everything is convenient and several buses (I took 61-C) will take you right to CMU or Pitt. My wife (to-be at that time -- we got married in the 'burgh right across from CMU as a matter of fact) lived in Bloomfield and loved it. The riding in the area can be fun as well, so long as you avoid pot holes on some of the back streets. You'll like it there.
