While I was in Madrid, I visited the Wax Museum, the Santiago Bernabéu Stadium (I swear I enjoyed this as much as the boys), Plaza de Castilla (where there are two twin buildings called Gate of Europe, that are 115 m tall with an inclination of 15°), Parque del Retiro (a really big park, I thought I was going to die after a walk to it and around it) and many more. And of course, I did some shopping too.
I'll probably edit this post later, well more like tomorrow, and add some photos. I took many photos of some buildings or monuments because I love the arhitecture in Madrid a lot! I'll update with photos of what I bought too. ^^
EDIT:
I forgot to mention yesterday that I love the public transportation in Madrid. It takes for maximum 10 minutes for the next bus, train or subway to come. The one thing I regret is that friend from USA was in Spain at the same time with me, but in Barcelona, and I didn't meet with him. But maybe next time, in another country we'll meet again ^^. Here are the pictures, some of them (WARNING: so many pictures):

Yes, the water is this clear and the fountain is really clean
