New York - accommodation?

Anyone know of any hidden gems, in Manhattan preferably?

I'll be there in November for a few days but the friend I was staying with was so traumatised by the prospect of my presence that they've since accepted a job offer in London. Typically, it's the week of the Marathon and Election so with accommodation bordering on extortionate at the best of times I'm struggling to locate anything that doesn't require a limb or a first-born (knew I should have kept Maddie alive).

Usually I'm fairly adept at ferreting out a reasonable deal, but even given the weak dollar what I'm finding so far is shocking. Doesn't have to be palatial by any stretch of the imagination, just clean and most importantly for a laaaydeee on her tod safe for myself and my kit.

Any steers gratefully received, thank you.
Thank you for the pointers chaps; the Vanderbilt's location is spot on and the cost a little less embolismic, however they're only offering me shared bathroom facilities - which in a Snowdonia campsite is a social must but in NYC a no-no.

Bit of hoikage for today's lucky viewers.... any more for any more?
