Good luck in your studies. Rhode island as a whole is safe. It is not as safe as it was say a decade ago but safe all the same. Can't speak on affordability I live in Newport rhode island 50 minutes south. But college hill is very beautiful. Just be vigilant. There are many sub pockets of rhode island that are more dangerous than others. Be especially mindful of providence place mall don't go alone. It has gone up in crime year over year. Rhode island as a whole is a vibrant state. Tiny but potent. As others have said pack for all 4 seasons. Generally our winters aren't too harsh but every year is different. This year our fall is extra cold probably due to the droughts of the summer and also cold air from Canada.
