If you're a fan of Sex and the City, you will recognise this place with no doubts. Contrary to popular belief, Carrie Bradshaw's Apartment does not stand somewhere on the Upper East Side (like it's mentioned in the series) but here, on Perry Street.
Tourists come here to take a picture on the very same place Sarah Jessica Parker stood while recording the popular romantic comedy.
It is a private building though so there are no tours and you cannot get inside. In fact, you should not even stand on the stairs while taking your pictures because those are the private property of the legal owners of the house.
You can get here from the subway station Christopher St - Sheridan Sq (lines 1 and 2) or by bus M20, 7 Av S/Waverly Pl station.
