We really enjoyed our time at Enza's place. Everything was neat and tidy, the bed was quite comfortable, and the bathroom was great! The location is overall really wonderful–for us it was really important to be square in the center of the old town and really helped us enjoy our time in Bari. However, the piazza outside can get a bit noisy on the weekends. I had no problem sleeping, but if this could be an issue for you, be sure to bring earplugs!
Check-in was really smooth, and Enza and her husband accommodated us even though we got in quite early, around 9am, letting us drop off our bags and then return later to grab the keys.
