Searching for a sommer job / internship

Hi!

I am looking for an internship or summer job starting in July for a duration of 2-3 months. I would like to find a job in the areas of sales, customer relationship management, key account management, but I am also open to other student jobs (such as a surf camp), and am willing to travel. I would like to stay in Europe, preferably in Germany or Spain. It is also important to me to explore the city and meet new people. Therefore, my question is: do you have any recommendations for what I could do or any locations to recommend?
