Oakland - Where campus is, undergrads. It's divided into sections. "West Oakland" on the map above is where Scaife is. Central Oakland is where the Cathedral of Learning is and all the undergrad buildings.
South Oakland - Cheap places, many of which are falling apart, lots of undergrads, can get pretty loud. There are some nicer sections where some med students live but in general I wouldn't recommend it.
*North Oakland - Junior/senior undergrads typically live here as well as many graduate students (there are a couple leasing companies that will only lease to non-undergrads). A bit quieter but there are some off campus frats there that can get a little loud on weekends depending on what street you're on. Main buses run through here as well as the Pitt shuttle which drops off right in front of Scaife. Pricier because of convenient location.
*Shadyside - Probably most popular place to live. Despite name, it's one of the nicest neighborhoods (think shady because of trees, not because of sketchiness). Again, you can access all the main buses and be at the school in less than 15 minutes. Lots of places to eat, grocery store, hospital where you can rotate for IM and surgery, and shopping.
*Bloomfield/Garfield/Friendship - This is close to Children's Hospital. Older neighborhoods, cheaper, many houses. Several people live out here, but there are fewer buses that connect them with Oakland. A bike would come in handy here.
Lawrenceville - Used to be worse but has been gentrified, now is the "hipster" neighborhood of Pgh. They literally call Lower Lawrenceville "LoLa." No idea about how much it costs to live there, but there are a lot of new, good restaurants. Probably one of the reasons Pittsburgh is #1 in Zagat this year. Harder to get to campus from here via bus.
East Liberty - Another neighborhood going through gentrification, there's a pretty big divide in SES living here which is a topic of debate. Generally cheaper to live here, but they're building a bunch of fancy new high tech apartment buildings there, right across the street from dilapidated store fronts and Section 8 housing. This is also where Target is, down the street there's stores like Anthropologie and West Elm. It's weird and somewhat uncomfortable. I feel totally safe there, even alone at night, more like uncomfortable because of the stark divide and the middle to upper class take over.
Highland Park - This would be a little too far away for my comfort, but people do it. Nicer area, lots of houses, lots of doctors. Probably pricier but I'm not sure. This is where the zoo is! Had a friend who lived adjacent to the zoo and could hear lions roaring from her place.
Point Breeze - Bit longer commute (15-20 min) but doable. Lots of apartments in houses, decently priced. Couple blocks away from Trader Joe's and the relatively new Bakery Square with fancy stores and stuff.
*Squirrel Hill - A bit farther out, you can find some cheaper places, older neighborhood again with a ton of places to eat and shop. There is a large Jewish community in SH, ton of doctors live here. Several buses run from SH to Oakland but not as much as Shadyside, and it's farther so it will take you a bit longer to get to school. Closest hospital is in Shadyside.
Greenfield - I just think of this as "a little past Squirrel Hill" because I don't exactly know where SH ends and Greenfield begins
😛 Some students live here, pretty much the same applies as SH.
Regent Square - Pretty much all houses, a lot of doctors live here. I know a couple med students who live here but they're married/families. Pretty far away from campus but the commute is doable. This is a really really nice neighborhood if you're coming in with a family.
Southside - I would not recommend living here. Apartments are hella expensive in the newer area of town, and the older side has a lot of bars/clubs that are loud and more of the undergrad scene. Fine to visit, not to live.
Also rule #1 of Pittsburgh is to avoid crossing a bridge or going through a tunnel on your commute. Despite being the "city of bridges" and having multiple tunnels to get in and out of the city, Pittsburgh drivers are afraid of the tunnel monster and there will inevitably be traffic on any given bridge/tunnel. Basically disregard everything below the Monongahela and above the Allegheny in terms of living unless you want to spend like an hour trying to get into campus in the morning.

If in anyone's apartment/house search they come across a place or an area they want to know more about, feel free to shoot me a PM.
Edit: Just went through and starred the places I'd highly recommend in terms of ease of getting around, quality of living, as well as price (somewhat).
