A 1BR apartment in NYC for $700/mo in 2013? I can’t imagine such a thing exists unless it is in the far reaches of the lost Island of Staten.
You’re exceedingly lucky to rent a BR in an apartment where the LR is also rented out, in the Bronx, the lesser parts of Queens or the scarier parts of Brooklyn for $700/mo.
You have to be lucky to find someone renting out their kids old room or something, friend of a friend sort of thing.
