Secret cocktail bar set in a 17th century library. From the outside, it looks like an old charming bonsai shop. You can only access with reservation. To make the experience even more exclusive, visitors must enter a secret code in a small and discreet door.
One of my favourite places to enjoy a beer bathed in orange lights and layered walls. They used to give concerts downstairs. Unfortunately they got recently banned due to boring local regulations - hopefully, live music will return soon amongst their palm trees and tropical lights.
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.
A piece of Egypt in the city centre. This temple, a gift from the Egyptian government, was taken stone by stone from the valley flooded when the Aswan Dam was built. It’s a great place for a picnic in the summer. You can enjoy the sunset and the (grey) skyline of Madrid.
After long hours at Reina Sofia museum time for going to Outer Space. It's called NuBel and it makes you wonderfully dizzy. Or, better, go there just before the museum - drink some wine and go to admire Guernica in 3D.
