Applying for housing at CCSU may seem confusing at first, but after you complete the process once it becomes extremely easy to breeze through it again when the time comes to re-apply. It's done completely online with a general lottery determining what time you can apply and pick a room, and even if you get a later date, you're still likely to get a room in the building you want.
The residence halls are generally a comfortable, convenient place to live while attending classes. Smaller buildings have great tight-knit communities of students, and the RAs do an awesome job of trying to keep residents engaged with daily programs. Everything always seems clean and organized, and there are good lounges, kitchens, and laundry facilities. The halls located "down the hill" are closer to most of the academic buildings and the dining hall, while everything "up the hill" is closer to athletic facilities and the library. So depending on what type of student you are and what activities you'e involved in generally dictates what halls will be more convenient to live in. The student population is made up of many commuters and in-state students who frequently make trips back home, so unfortunately, the campus does get pretty quiet on weekends. But, there are tons of activities, sports, and club meetings happening almost every day and night to keep things entertaining.
My freshman year I lived in Seth North Hall which is a freshman experience dorm. I would recommend living there if you have difficulty making friends and would feel more comfortable living with students in your same position. However, the environment can become suffocating as gossip travels fast and since the dorm is composed of all freshman it very quickly begins to feel like you're back in high school. Basic housing is around $10,000 a year and the quality of the residence halls is average for what you pay. The suite style buildings and the newly built residence hall charge a little more per semester and I've had friends tell me it's worth the extra money. Overall, I was content with my first year housing experience; it wasn't great and it wasn't awful, but what I expected.
