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.
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.
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.
