I spent three wonderful days in Bari at Mario's place. First of all, Mario is a really nice and easy-living man. He does his best to make your stay at his place the most comfortable and enjoyable as possible. For instance, he proposed to pick me up by car at the train station and gave me a few advice about Puglia. Moreover, Mario is a great musician and someone you can talk to easily.
His house his very warm and pleasant. It is really close from the sea and 5 kilometers far from city center. There are buses near his place that takes you quickly to Bari. And by bike, it's only 20 minutes from Mario's house.
I would suggest at everyone to stay a few days with Mario in Bari to discover this wonderful part of Italy and this great man.
