Foxy Boxes remains inaccessible to the fledgling unless they partake in a quest received from Knox Harrington. The interior of Foxy Boxes appears to be a basic warehouse with two stories. In one of the rooms near the entrance, the fledgling can find in the computer reports detailing that they were being spied the entire time in Santa Monica by the quest target, the Asian Vampire.
The second floor of Foxy Boxes is the physical location of the apartment in which the fledgling was Embraced during the intro cinematic. The Asylum and Diner can be seen out the windows. This apartment doesn't exist when you gain access to the interior, however.
