You won't find a more helpful host than Diran, what a lovely guy. The apartment is right by the beach, good transport into downtown Bari although we walked (40 mins) past the port. He recommended a great restaurant, La Uascezze, where we enjoyed the best meal I can remember! The apartment itself is spacious, traditionally styled, in a historic building. There's a great market nearby (think Whole Foods Market), and the Lido for beach fun. Bari old town was great to explore, we only stayed one night but it was lots of fun and made better by Diran's willingness to answer questions and provide suggestions.
