I think most folks at YC weren't aware I was coming alone with Adam until well into the batch. They did go above and beyond to put me in touch with a housing advisor while I was in the area for interviews. The problem was that I was only staying for three months, too short a period to rent an apartment cheaply, and there didn't happen to be any women founders' shared houses in my batch.
In case it didn't come through clearly enough in the article, I should reiterate that the YC partners and my batchmates were super supportive and often went out of their way to make it easier for me to participate in YC events - offering rides, allowing Adam to tag along with me at office hours, helping to entertain him, and generally being extraordinarily patient and welcoming.
