Going to visit New York in about 6 months

Just got a mail that they did some mistake with my flight booking, so I am getting a cheaper flight that goes
direct, no stop in London or whatever.
Still not sure about the hotel, found some, but a friend of mine wants to come with me. He doesn't know if
it's possible at that time, but it would be cool, because we could get a room together and save like 100€ per
person.
If somebody knows a good, cheap hotel, I am all in-seems like I am going for 11 days instead of 2 weeks, but
that's ok for me, that way, I've got more money to spend :D
