Tarragona is a great city to combine culture with a good cuisine under the mediterranean sun. You can enjoy the party life to get to know local people while learning a new language. Tarragona is a great place for your Erasmus experience because of its diversity and the proximity to other great cities like Barcelona, Salou, Girona and Valencia.
