Spanish summer language school in Spain, which city?
I’m going to spain in august for learning spanish for 1 month, but I cannot decide which city should I choose, since it will be the only holiday for me this summer. I want to spend most of my time in beaches, and I want the city to have a nightlife (not necessarily clubs or bars but where people go to city center or beaches at nights instead of a sleeping city), so I think Barcelona seems to be the best choice but I’ve been there and I want to see other cities. Also I want to go to a safe city, if possible 
My choices are: Tenerife, Valencia, Barcelona, Alicante, Marbella, Cadiz.
Any help would be useful, also if you can give some information about these cities it will be great!
all cities that you refers have a very good nightlife , do you know that spanish people likes the bars, live outdoor and talking with other peoples.
Cadiz is very little the other cities are bigger, but Cadiz es very cool , the old city remember me La Habana in Cuba.
Remember we are very bad with foreign languages, but we are very happy and hot people.
