My wife and I are going to Spain in September 2023. It will be our first trip. We are flying in and out of Madrid. I'm looking for some advice on our itinerary/order of travel. Taking out travel days, we'll be there 8 days.
Along with Madrid, we'd like to visit Barcelona, Granada and Seville. I'm looking for the best order to visit these places, and also interested in best modes of transportation to each. Also open to accommodation recommendations.
