We felt great in Bari, it's a great city! Also, the place was a great retreat from the tumultuous Italian nightlife - it is located in a good and safe area, close to the old town. Walking to the free beach (pane e pomodoro) was quite a pilgrimage, but you can always rent some bikes or use the public transportation system.
We loved it, because it was clean, close to the most touristic attractions (bars, restaurants, museums, central train station) and quiet. Also, the kitchen is fully equipped with everything you need. The hosts are very kind and helpful, you can turn to them with any problem you have!
