Absolutely recommended. The apartment looks like exactly as you can see it on the pictures, and Enrico is a great host. He gave us a map with a lot of panificios, restaurants and cafés in the area, and he took the time to take a pen and drew even more places on the map.
The best thing is the market opposite to the apartment. Many local people, friendly prices, amazing food.
The only downside is you'll have to walk 15-20 minutes to reach Bari's old town, but if you plan trips to visit the area (you should, Polignano and Matera are both must-see places), the railway station is quite close.
