Spanish artist Jaime Hayon is sometimes called Almodóvar of design. So if you like "Kika", colours, Spanish culture and dreamy aestetics, you must visit Barceló Torre de Madrid and stay there for a night or just have a drink in a golden bar.
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.
Barajas Airport is so inspiring, a vibrating place to come and go. Love to walk in its roller stairs and watch the organic columns and the wavy ceilings changing colors from blue to yellow designed by the architects Richard Rogers and Estudio Lamela.
