Susan and Marco are bloody fantastic (and so is their lovely apartment)!
We recently spent 11 nights in their perfectly located, spacious apartment and felt entirely welcome.
Make no mistake, you will be staying in the best place from which to explore New York. Although we found it very difficult to leave Williamsburg (so much going on there) Manhattan was just one stop away from either of the two subway stations that were a few minutes walk from the apartment.
We had a very private space cordoned off for us including our own bathroom and sitting room. The bedroom was lovely with a supremely comfortable bed and a big screen TV with full cable.
We would unreservedly recommend staying with Susan and Marco and want to thank them again for making us feel so welcome.
