Nevermind I foudn the fic. 
I don't remeber much about this story, but what I do is: 
After the chamber incident Harry is changed do to the basilisk venom, he then leaves the Dursleys and ends up in a hotel/safehouse which has some other magical creatures there like a drow and vampires. Any help locating this story would be appreciated.  Thank you in advance.
