In an earlier posting I asked about spending 10-11 days in Spain at the end of December, traveling by train from France with my daughter. I've decided to focus on Barcelona (first) and Sevilla, with a side trip to Cordoba, and forget the coast and Tangiers, but as we must train through Madrid to return to France, I'm wondering if that would be a nice city to spend New Year's Eve and Day in. Any suggestions will be appreciated.
