Calle Convento de Jerusalem 9 is a very safe place...it is a mix of Chinese restaurants , stores, groceries...it has Mercadona a relatively big supermarket! Very convenient to the train station, old city, to metro and buses and cabs . the studio was impeccably clean and we felt very comfortable and safe! Ignacio made himself available if we encountered any issues...which we did not. It was overall a good visit!
