In September, I would like to spend a week or two in southern Spain and enroll in a school to learn Spanish. I want to meet people, improve my lower-intermediate Spanish and see the place. I am thinking of Cordoba or Sevilla. Can anyone recommend a school? I am interested in culture, history, art, walking, enjoying the atmosphere of the place, and might also like to visit nearby towns.
Some of the things that might make a difference: I'm 50, so would like something with some people who aren't just in their 20's if possible (say, around 35-65 approximately). Granada isn't an option as I don't want to be in the mountains (I live in the mountains). (Malaga could be a possibility, too, but I'm more interested in art, history and culture than the beach.) People say Cordoba is wonderful, but is there enough to do there for a week?
Is there somewhere else in the south that anyone would recommend? Thanks so much!
