We love to peek inside expensive homes, especially if they’ve been occupied by celebrities. This time, however, we’ve found an apartment that’s located next to a different kind of celebrity, known as the Queen. The $18 million apartment is located right next to Buckingham Palace and has been designed by one of its architects. Seems like a lot of money for an apartment but for the same price you might also get a peek inside the Queen’s mansion. Seems worth it?
