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.

Best organic ice cream I've ever had!... so far ;p

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.

Very charming French bistro in the heart of Justicia. Quality food and great service, especially Pablo (one of the owners) , A fantastic host!

Rooftop party with such a view. Should I add anything more?
