I found the place I’m living now (been here a year and a half) on Roomster. They were literally the first guys I messaged, there’s been essentially 0 issues with any of the 5 roommates, and since we’re splitting 5 ways my rent is obscenely cheap - 370 a month plus utilities in a decent neighborhood in New Haven proper. Obviously not everyone will get as lucky as me, but worth checking out the site. The one downside was that I did have to pay for a subscription to send messages on Roomster, I think it was like $12 a month, but I only needed the one month.
