What could I said about Madrid? It's a nice city for sure but to me it's lacking the element of fun and charm. I frankly prefer Barcelona better because of the colors and uniqueness of the Antonio Gaudi architecture and how it's influent the creativity of the people of the city.
Whatever it is, this is the Capital City of Spain and one thing for sure I really love Parque The Retiro in Madrid. :-) It's really nice to be sitting there doing nothing but watching people and the day gone by.
