My husband and I will be visiting Andalusia for a week (or more) starting in mid October. We prefer to use public transit than have to drive a car. So, I was thinking of selecting Cordoba as the place to get an apartment. From there we could do train travel to overnight one or two nights each in Seville and then in Granada.
We are retired, so we can be leisurely and take our time. (Time lost to train travel is not a disaster for us.) Any advice on Cordoba as a base? (We will have already had a week in Madrid, with side trips, and a week in Barcelona.)
I also welcome any other "must see" advice for Andalusia, especially if we don't have to rent a car.
