I can’t believe I haven’t come across this website before today. MadridFree is a daily updated site featuring the latest exhibitions, concerts, special events and other cool and interesting stuff that you can do in the city FOR FREE. The site has an English section too, although it’s clear that most of the articles have just been put through a translator program.
Each event is illustrated with a photo and there is a categorised list for easy navigation to the event type of your choice. You can also subscribe and get the latest events auto-fwded to your inbox / twitter / facebook account etc.
This site is going in my sidebar. Muy bueno!
