AMAZING LOCATION - so easy to get to everywhere, Union Square subway just round the corner and a couple of lovely restaurants on the doorstep. Compact studio flat (i'd say better for one than 2) but provides most things you need. Make sure you are fit as those flights of stairs are a killer! Its a little awkward getting suitcases up and down as well, just make sure you take that in to consideration when you book.
Otherwise, for the price and location its a steal - you wont spend much time there anyway, and it is a well placed base, with a comfy bed! :-)
