We had a pleasant stay for four days at a clean and tidy Giovanna's place.
It is located not far from the city center, you can easily walk to the old town and to the beach. The railway station is reachable in a max 15 minute walk.
The windows of the flat face a typical narrow street, but it is not noisy inside as the traffic seems to be almost local.
The only disadvantage I would say is that the small room with two beds for the children has got no window, but to keep the air circulation it is connected with the spacious bedroom by the window high up in the wall between them.
It is quite comfortable to cook food at home.
I would recommend to check the working hours of the supermarkets, greengrocers and so on as they close for "siesta".
Have a good stay at Giovanna's place in Barletta.
