I visited for a month and would suggest that the visit be around that time. It gives plenty of time to do and enjoy just about everything the city offers. Traffic didn't bug me as much since I walked just about everywhere. I would suggest finding a place to stay at in Long Island City as it is the most convenient if you are on a tight budget. New York really wasn't on the top of my wish list either to be honest - I would have much rather preferred Italy, Turkey or Alaska. But that's just it - I kind of wanted to disappear and feel 'lost' for a while; You really don't feel alone, at least in my opinion. Hope you do consider adding it to your list, I would recommend the visit.
