Perfect location for the nightlife of Agrigento. Via Bus to valley of temple (1,20€ ?) from main station (5 minutes walking). Via Bus to Scala dei Turchi from Piazza Fratelli Rosselli to Porto Empedocle (Bus goes from Agrigento to Porto Empedocle and back, but you can exit and catch it again at the Restaurant "Sapore di Mare") (3€ ?).
Be aware that due to its location you'll hear the bars around depending on the season maybe until 2 or 3 am.
