I've lived in Martin for 2 years. It has its ups and downs.
The real advantage is that it costs half what anything else in the neighborhood does. Also, now that more medical students live here (when I started, it was empty,) you'll have alot of friends and there is definately more social cohesion here than the other buildings, which are like regular apartments (except that the rent system for Barringer and Orlowitz is basically extortion.) I like not having bills to pay; internet, heat, A/C, electricity are all free, and every floor has a cable TV in the lounge.
The downs? If you're a fan of crystal clean kitchens and facilities, Martin may be... well, the custodial service here isn't very active. Personally, I also like having my own bathroom and kitchen, so living in a dorm has been a bit wierd for me.
If you have more questions, let me know.
