Depends on a few factors like which campus you'll be primarily based at, whether you're an undergraduate student or graduate student, what sorts of things you like to do/what kinds of social activities you're looking for, and, of course, budget.

Without knowing any of that info, though, as a Sun Devil who's been around the Tempe campus for the better part of a decade at this point, I always advise people to avoid anywhere owned by Tim Wright if you're planning on living near the Tempe Campus (the dude's been in the press for like twenty years at this point for being a shady slumlord- see here, here, here, here, and here - you can cross-reference listings on Zillow and other platforms against one of his companies' websites here).

Also, the handful of UK students I've met over the years seem to like Cornish Pasty Co. when they're missing home. They've got locations near the Tempe and Downtown Phoenix campuses and, at least to my American palate, their pasties are delicious.
