The original design of the Kiev-rank was to accommodate one thousand five hundred to one thousand seven hundred crew members, so after installing a plethora of weapon systems and necessary equipment, the internal space is indeed cramped.
But as a yacht, it obviously doesn't require that many people.
Moreover, modern ship control systems can fully achieve operation of this giant ship with a small number of crew members, so naturally, it doesn't require as many personnel.
And with a significant reduction in personnel, it naturally frees up enough space inside the cabins, combined with the reduction of numerous militarized designs, and the use of modern ship technology, advanced by decades, to redesign and plan the internal structure, making the ship's interior spacious enough to accommodate luxurious main cabins, and various other lavish amenities.
