I staid a week at Stefano's apartment.
It was a perfect place which served exactly my needs.
A small studio is clean, easy go in, go out from a building. It has a perfect location, 7 min to walk to a Central train station and even shorter distance to a closest subway station. 25 min to walk to old part of Bari. From a Central station there is a bus as well to old Bari, Port and a local beach.
In the apartment there were everything I was needed.
Stefano is a very frendly and caring person, ready to help if needed. I would recommend that place to my friends and would stay there if a next time I am in Bari.
