I've read the back and forth comparing Madrid with Barcelona, but I am still undecided. I have not been to mainland Spain - only Mallorca. I am taking my daughter to Spain for her 16th birthday in January. The two of us will have three full days, wherever we go. She speaks a little Spanish, loves art, fashion and food. I am looking for a walkable city and Madrid looks too large for such a short time. However, the museums are a huge draw. I don't want to spend a lot of time on public transit or in cabs as we have such a short time. I'm not sure what Barcelona (besides Gaudi) and Seville have to offer in terms of food and museums, but both seem a pleasure to walk. A little more info: we LOVE to eat and art is a must. This is her first introduction to Europe, and I want it to be manageable and not intimidating, so somewhere easy to get around is also a plus. We are not taking any side or day trips. Thanks for any helpful advice!
