I waited my whole life and was not disappointed!
Greco, Goya, even a Rembrandt oh my!Bring your walking shoes and a tour book. (If you are a teacher they advertise free admission but would not give it to me because I did not have the appropriate id. I could not figure out what an appropriate Id was since I had several id's with me. I am guessing they wanted a picture id from your school, which I did not have.But the person at the box office was vague and rude.)Speaking of rude, The staff are a bit rude in general but who cares you are at the one of the world's top ranked museums seeing the greats. The admission is cheap 6 eruos which is about 9 bucks USD.I don't know any local museums in the US that are even that cheap, never mind the fact that you are at this famous great! Lots of walking, be prepared and awake. Spend 6 or more hours here. They have free admission a few hours in the late afternoons several days a week. (Not sure the days but I know Sunday is one of them). so break it up if you can as an option too if you can't walk as much. But no matter what be prepared to wait. The lines are very long but they do go pretty fast. I am guessing in the summer it might be very bad, we went in March. After here make sure to visit Retiro Park which is so beautiful you can just cry! Outside the museum they had some cool statues outside on the street. Enjoy! PS- tsk, tsk, tsk no photography allowed inside the museum of course.
