Overall good experience

The experience was great—living with other French and international students, going to school in the Latin Quarter, etc.—leaving me with only two main complaints. Firstly, NYU housed students in the Cité Internationale Universitaire de Paris (CIUP), which was disastrous; far from campus, a completely useless staff (who often weren't there, often leaving the building completely unguarded with no security), trashy unfinished rooms, etc. My understanding is NYU no longer houses students in CIUP.
The other main concern is they do quite a bit to baby students; many students talked about how with how much hand-holding there is, how many strict/specific rules there are, etc., it felt more like a high school program than a college program.
That being said, the professors are all excellent and incredibly qualified in their respective fields, NYU spends a lot of money on providing programs for students, and, of course, living abroad for a semester any way is a very enriching and eye-opening experience.
