I have read a number of past post, however I still need some help. So, thanks for reading this and thanks for all opinions. We have visited both Barcelona and Madrid in the past. We are looking now to spend the month of mid-February to mid- March in southern Spain because for the weather and culture. The number of days are flexible. But nothing shorter than 15 nights up to 30. We have considered Valencia, Seville and then Malaga. All three on the same trip. Normally we like to stay in one place for a month and just sink into to it. This time we want experience at least 3 cities for a future return. We don’t like moving around every couple of day. We choose these three cities based on reading and some of what friends have said. We are from San Francisco, so we love water and city. Walking and finding out own way. Not tour people. We always rent a place on on VRBO or Airbnb. We don’t want to read a car. We love the trains.
Any and all recommendations will be greatly appreciated.
