I am currently halfway through the third book, and every little bit addicted to the story of Christian Grey (fifty) and Anna Steele. The Escala penthouse referred to is real, although the images and floor plan don't match the descriptions in the book (no secret rooms) there are still many likenesses. The apartment on the top floor of Escala recently sold for $6 million, the all-glass window home marketed with Grey’s famous piano in the corner.
