I did my undergrad in Pittsburgh and I must say the city is great. It's a friendly and clean urban environment.
I spent some time at Duquesne. It has a rich history and maintains a beautiful urban, yet isolated campus. Furthermore, the Big 3 pittsburgh schools, being Pitt, Carnegie-Mellon, and Duquesne, all have close ties which makes a med app to Pitt's med school a good choice.
As for Duq. program, it is not on the level of Bryn Mawr, Scripps, Goucher, HES etc. but it is strong and is placed in Pittsburgh, arguably one of the largest medical hubs in country with UPMC. It also has linkages with Temple Med and Lake Erie OS.
Hope this was somewhat helpful.
