I don't have too much insight into the school, but I do know they make you feel very special. I applied there this past year, and was invited to interview. I got countless letters from the admissions department, the dean, etc, all telling me more about the school and providing useful information. I mean, every school sends a letter or two to let you know you've got an interview and maybe give you some info, but Dartmouth went all out. When I went to interview it seemed like that helpful, caring attitude that I saw in their letters applied to everyone's behavior in person as well. I got a really good feeling about the school.
I was very turned off by the location, however. It was way too remote and rural for me, and I couldn't imagine myself living there for 4 years without going stir-crazy. That's really personal preference, though. I like big cities and lots of activity, whereas many other people would love the peacefulness of the setting.
Also, the hospital was INCREDIBLE. It was so beautiful, light, and cheerful, and not at all like most hospitals. It's designed like a mall, with high ceilings, skylights, and overhead walkways (a lot like Arden Mall in Sacramento, for anyone who's been there). I would have loved to spend 3rd and 4th year there, if only it was near a city. Also, the students I spoke with were very happy, and none of them seemed to think the location was too much of a problem.
I think it's definitely worth adding to your list if you don't mind the location.
