Believe it or not! But, there are over 2000 lavishly gilded rooms in this luxurious palace or rather living museum. Check out even the ceilings because they come beautifully decorated. If possible it is always wise you get hold of a guide which elaborates on the particulars and history weaving behind the rooms. And if you are tired of walking around the place, look towards west and a beautiful view awaits you there. You can find an armoury museum attached to the place. Also halt by the nearby church and the crypt under it.  A must see attraction in Madrid!
