The Duke and Duchess of Cambridge live in Kensington Palace with their three adorable children Prince George, Princess Charlotte and Prince Louis.
Apartment 1A, which was previously home to Princess Margaret, has 20 rooms over four floors, including five reception rooms, a night a day nursery and dressing rooms.
We've seen a few snaps from inside the stunning building since the couple moved in, but as it's their private home we don't know much about it.
But Kate and William shared a lovely photo of the outside of Kensington Palace to mark Easter Sunday, to the delight of fans around the world.
