I love the ICO RC. I stayed there all 4 years. Fast WIFI, pretty modern facilities, piano, lots of open study areas, meal plan, adjacent to the school. I thought the rooms were huge. My only gripe is the lack of ceiling lights makes it dark unless you bring your own lamps.
You usually have 3 exams a week that start at 8:00am and so forth, and it really hits the spot to be able to immediately eat lunch/dinner 100 ft across from the lecture hall when class is over, or go back for a nice nap.
I met a lot of cool friends and got to know upperclassmen/lowerclassmen, and generally had good times. I'd say the RC is the popular choice: it's mostly freshmen with maybe 10-15 students per upperclass returning.
