As a 4th yr at Georgetown I think I can offer a couple of insights:
The IM is pretty strong. In terms of "rank", I think its fair to say that it isn't in the same league at MGH/Duke/Hopkins. I think it is just behind Columbia/Northwestern/BI/Penn.
Georgetown rotates through 4 different hospitals, so you get the university, V.A., and community hospital experiences. Georgetown is a fairly tradition bound program. But I think there is an excellent working relationship between attendings and residents. There probably are only few attendings that people dread working with. Which I think is the same any where you go.
You work hard there, but there is no scut. It is a rare instance for an intern to do any blood draws, transport, etc. The nursing is good and getting better. And with the institution of the 80hr wk, it has become very reasonable place to work.
The worst problem is the misconception of GT after being bought by Medstar. Many applicants were scared to come to a financially unstable hospital. The quality of the applicants did drop. You saw less and less students from Michigan, Northwestern, Cornell, Penn, and other top med schools. And the tradition of 10-12 Georgetown students staying (usually the best/ AOA's) at Georgetown stopped. But the quality of teaching, support, and work really never changed. The key attendings that make the heart of the program never left. So the kids who Gtown had to dip lower on the match list to get, ended up getting the same superb training.
If you want to come to DC, I think Georgetown is only second to Johns Hopkins in the area. And with the upcoming merging of fellowships with Wash Hospital Center, residents will have a great inside advantage into getting some great fellowships (esp in cards, gi, and endo).
