Though you might say the city is full of colors, from Velazquez's tones of greys to Miro's vivid strokes and shapes. From Goya's darkness to Picasso's blues, Rastro's potency and variety of people and fabrics, or even shop windows for tourists full of Sevillanas and colorful magnets - the biggest canvas is above all of us. It's hard to beat the intense blue of Madrid's sky. I have no idea if Giotto has been here, but I'm pretty sure he was inspired by Madrid's sky to paint Padua's chapel's ceiling. The smoothest blue of Madrid's sky lies in contrast with the dryness and ocre buildings and landscape gives me torticollis. The colors may vary from mediterranean sea, Yves Klein Blue and Pantone 293C. It doesn't matter how it's defined - it is, for me, a boost of cheerfulness in any place and mindset I find myself in. I won't be able to touch or reach the blueness of this sky, but it touches me. Deeply. And I happily allow it.

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.

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

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.
