Having a small espresso machine in a dorm room should not be too difficult. Water from a fountain will be sufficient for filling your tank. You just need a pitcher to carry the water back to your room. Or you could use bottled water. A small hand grinder, a tamper, some cups, and some coffee, and you're in business. You also need a place to clean up, wash cups and baskets and so forth. The bathroom on your floor should do.
One of the dorm rooms I lived in when I was in college had a sink. I had a percolator and I perc'd two or three pots of coffee a day, and the sink made it easy for me to keep my percolator clean. Another room I lived in didn't have a sink, but the bathroom down the hall was still adequate for washing my coffee pot and cups. Most dorm rooms aren't spacious, but I always had enough room that I could have devoted a square foot to an espresso machine, if I'd had one.

Lelit make it seem like a reasonable choice for a dorm room. I don't know how well it performs, but you might search for reviews. It's a little more expensive than the Illy, but the cost in consumables (coffee) will be lower, as pods are rather expensive.
