Hey there! Sorry this is 2 weeks delayed, I kind of forgot about SDN for a while.
Favorite: I'm not from New York and I absolutely LOVE living here. While we're not exactly in the heart of Manhattan, it's not really a huge deal since you're gonna be too busy to go out on weekdays anyway. I have loved exploring the city during free time (of which there is plenty during M1-2 and 4). It's actually kind of nice being a bit removed from all the distracting fun stuff so you can really get stuff done during the week. Second favorite, in case you're already a New Yorker: We are affiliated with Montefiore which is a MASSIVE hospital system, plus a bunch of other hospitals in the area. This means that there's a huge amount of variety during clinical years. The patient population is really underserved and there are a lot of challenges that come along with that (this is a good thing for our education). I've heard that doctors who train at Einstein have a reputation for being able to thrive anywhere. Oh and a THIRD favorite thing- cheap on-campus housing!!
Least favorite: Sometimes things are really disorganized with the administration. They mean well though and are always taking feedback and working to improve.
Overall, I am very happy I decided to go to Einstein. I feel like I'm receiving a very solid education, and our match list is always fantastic. P/F during M1 and M2 was amazing, but of course this isn't unique to Einstein (but I seriously recommend that you prioritize this when deciding on a school). If you want to be in New York, I'd definitely recommend it!
