I will be in Sevilla this summer doing a language immersion program. My 15 year-old daughter will be with me, studying, as well. We plan to spend 7-10 days traveling during the first 1 1/2 weeks of August. (I know it will be hot!). Before we head up to Madrid and Barcelona, I would like to spend two nights on the coast with her. I am NOT interested in Costa del Sol scene! I would like to know if it would be possible to spend a weekend by the sea/ocean that is a little less touristy but that we could access by public transportation? Many thanks!
