Calle de Ruiz de Alarcon, 23, 28014 Madrid, Spain
I am not sure why you would need a review as an incentive, but here is one! As you probably already are aware of, Prado is one of the most famous museums in the world. Its permanent collection is one of the best, if not the best, among museums of its kind. Every room is full to the brim with iconic pieces, the great masters efforts on display. Personally I find the section with Goya's black paintings the very best of what the museum offers. Even if you aren't into art the Prado is well worth the price of admittance, as is the guide book that you can buy at reduced cost along with your ticket. I would recommend two visits, as it is easy to become exhausted while roaming Prado's vast halls.
I payed for a full ticket, with the guide book and audio guide (24euro plus 4 euro). The guide book is heavy, so, as recommended from the audio guide stand, I have only bought it from their shop at the end of the tour. The audio guide has a friendly interface and is easy to be used. Just that in a couple of rooms, the paints weren't the one as indicated (probably an internal error). But otherwise the experience is quite impressive.
Definitely buy tickets on line. Do not attempt to go without or you will make a ridiculous line. Also take your own comfortable ear buds for the self guided tours. We followed Rick Steve's suggested plan to see the best of the best, the must see paintings. There isn't enough time in a day to see it all.
Museum is definitely worth visiting. Free after 6p BUT there is a huge line that forms to get free tickets. Be there around 5:15p latest if you want to get in earlier. No photos allowed inside, of course. Magnificent pieces of art. Beware: if you do go in at 6p for free, museum closes at 8p and 2 hours is not enough time to view and awe everything.
You can get lost between all these gorgeous paintings. I spent hours in front of the Garden of Bosch, go straight forward to it and then rotate. Keep in mind everybody wants to perceive the details on the painting, sharing is caring. I wanted to buy everything at the gift shop!!! Beautiful stuff. Remember to share the audioguide instead of giving it back.
