Luiz's place is a bit further from the city centre and the main train station, but it is quite close to the beach and another train station. Since we were travelling also to places and towns around, we didn't mind that and the price for the clean, welcoming place was better than we expected in the first place. I really recommend Luiz's place if you don't plan to stay just in the centre of Bari. He can also provide you with any info you might need so don't hesitate to ask him! :)
