Donostia-San Sebastián (Basque: Donostia; Spanish: San Sebastián) is a major city in the Basque Country, an Autonomous Community of Spain. Donostia/San Sebastian boasts one of the best in-city beaches in Europe. It is quite unusual feeling that you can sunbathe and swim right next to major historical buildings and churches. Surfers are in abundance here.
