This is a fabulous Hotel called Silken Puerta América, where each floor is designed by a different architect. It is open for public visiting. This year the Hotel was hosting the art fair Just Madrid and I was totally amazed by the first floor design of my favorite architect Zaha Hadid.
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.
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.
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.
