Reina Sofia museum is always a good idea. And it's never enough of Picasso's Guernica as well as the other modern art gems. Save some hours for visiting and then look round the corner and have some wine at NuBel.

Going out in Chueca, the gay neighborhood of Madrid and grab a beer in the bars around is fun. One of my favorite programs is going to tranvestite´s concerts there.

Medialab Prado is the coolest place to work, to collaborate, to do workshops, to participate in events and conferences. They are the nicest people in the planet doing such interesting programs. My favorite is Interactivos. It is also a good place to meet new friends and go afterwards for beers in the bars around Lavapies, a district full of art galleries and Museums.

Nice restaurant...Nearly everything on the menu is from small, local suppliers.

A bar and bookshop to enjoy a glass of wine while reading a book or to read a book while drinking a glass of wine. They show a careful selection of contemporary literature and artworks downstairs, from where you can spy on the people upstairs because the ceiling is made of glass.
