Mazel tov on your acceptance!

Unfortunately, good subletting opportunities can be quite difficult to find most buildings explicitly prohibit the behavior.

I'm not sure how old you are, but depending on your age, you may be eligible for summer housing through studenthousing.org. NYU and Pace also have great summer dorming options, but they only offer housing for the entire summer rather than for specific time frames (which will likely be a problem given the nature of DreamIt's Israel-NYC time split).

Usually short-term rentals are very expensive (AirBNB certainly is), but http://www.nyhabitat.com/new-york-apartment.html seems to be the most reasonable provider around.

Of course, Craigslist is also always an option, but there are no guarantees and it helps to know a bit about each building/location first.

If you have any questions, I'd be happy to help out!
