I like to live the Christmas period. All our cities deserve nice surprises, with Christmas lights everywhere and other initiatives.
I'm particularly fond about Madrid and I can't miss to go there even if it could be only for a few days.
In that period the City is incredibly nice and uplifting.
Last Christmas I passed there a few days and to have had the chance to see how the people enjoy themselves (particularly the children) was uplifting, indeed!
Here attached you can watch a video that I grabbed last year that can give you an idea about that!
