Quad is very hard to describe exactly where freshmen are and which rooms are triples/doubles. Generally speaking, freshmen will not be housed on the third floor. Most of the rooms on the third floor are singles for upperclassmen. There are a few exceptions for corner buildings like Roebling. It’s also a toss-up on which rooms are triples/doubles. You can kind of look at square footage, but sometimes that doesn’t mean much either. Sorry this isn’t very helpful. I don’t want to mislead you.
You can bring almost any small appliance that you want, the kicker is that it needs to have an automatic shut-off for fire prevention.
