If you are planning to stay at Bari, I'm fully recommend you Nicola house. The flat is really nice with perfect (and huge) terrace. Next to the flat you have a lot smaller shops and bus station which is really helpfull to get to the city. Driving with car is problematic! :) If you are looking to travel all around the area by car it's the perfect home base
Nicola is the best host in my life, he was really a big support for me and my parents. We had a few of days in Bari and his recommendation helped us plan those days. Highly recommended by us!
