Giorgio’s spot is perfect for any solo traveler to Bari. It has a nice balcony that I enjoyed in the afternoon on both of my days there. All of the shared facilities (kitchen, bathroom) will be as clean as you and the other guests make them — which was very clean while I was there.
The apartment is set nearby the university and therefore full of buzzing bars and restaurants (Il Pane e le Rose is incredible). It’s just a quick walk down to Bari Vecchia, the old town. In additional to all of these pluses, Giorgio is a warm, helpful, and flexible host.
