Off to Madrid for 3 days next month with a friend and the title does what it says on the tin. The guide books rave about all of the art and musuems but that's not really our thing - I know that the Prado is a must but wondering if there is anything else that we need to make sure we don't miss? We're staying fairly centrally so will be easy to get about, and I know it will be uber hot so need to be careful not to try and cram too much in as well. I love food and markets, really want to see flamenco but other than that what should we do?
