The residence halls are comparable to what you would find at any other university, but we may have a few more perks.
We have two types of housing, University Housing and Private Certified.
University Housing
University Housing is through the university and most students choose to live in a residence hall through the university. Most rooms are doubles (although there are some singles an triples) that come with two beds, two desks, two chairs and two closets with locks that will only open with your key so your roommate cannot access you closet. The beds can be lofted to different lengths so keep that as an option. You can bring your own microwave or fridge or rent one from a company that the university works with. You also have internet but you need to bring your own ethernet cable, but if you and your roommate both bring one, you don't have to share internet because there are multiple plugs on the modem.
University Housing also has community bathrooms, but male and females have different bathrooms so it's not completely "community". There are usually 2-3 community bathrooms per floor, so you'll never have to worry about all the showers being taken up. Each bathroom is cleaned 2x a day and deep cleaned 1-2x a week.
All University residence halls have libraries and computer labs. We have library system at Illinois that you can request a book from one library to be sent to the library at your residence hall so you don't have to venture out if you don't want to. All computer labs have on site staff to help you if necessary and printing services in case your own printer starts to fail.
All residence halls also have lounges. A few of our residence halls are air-conditioned, but many aren't, but if you live in one that is not air-conditioned, it is just your room that isn't air conditioned. The lounges with TVs in them have A/C as well as the foyer, dining halls, computer labs and libraries.
The biggest perk to university housing is that you can eat at any other dining hall on campus that is also university housing. So you can eat at Busey-Evans one night, then travel to Illinois Street Residence, then to Champaign the next night if you want.
I lived in Busey-Evans both my freshman and sophomore years. It's all female, air-conditioned and I loved it!
Private Certified is housing approved by the university, but owned by a private company. Examples would be the Newman Catholic Center, Bromley Hall, Presby, Illini Tower etc
Private Certified housing (PCH) tends to be more expensive, but there are usually more amenities. For instance, the rooms tend to be suit-style so you would usually have your own room with a share common room and bathroom instead of community bathroom. Presby, for instance, is one of the most expensive, but features leather couches, nice furniture and a kitchen with newer appliances and Bromley has a beautiful lounge with an indoor pool.
The biggest downside to PCH is you can only eat at that residence hall and no others. However, if you miss lunch, some residence halls, like Bromley, will give you a "sack lunch" so you have something to eat even though you missed lunch.
