I stayed with 2 friends at Cosimo's place for 3 nights and to be honest we couldn't imagine better place in Bari. Flexible check in/out, localization in the center of the city, many useful recommendations about the city and area nearby. The whole apartment is much more bigger than you can imagine, very clean with all necessary equipment. It was definitely one of the best airbnb places that I've ever been.
Thanks a lot!
