The apartment is very close to the old city. In an area where its not noisy and not many tourists are on the street, which we liked. The apartment itself is very big on 3 stories and has 2 balconies and one rooftop terrace. We enjoyed every morning our coffee out there, which Antonella & her husband stored in the kitchen for us :-)
As we stayed there in November Bari isn't that warm anymore and so it is the apartment. During the night is was very cold also inside, so be prepared to bring warm sleeping clothes!
Besides that, we highly recommend to stay there!
