My friend and I had a great stay in Giovinazzo and around Bari. We've been here for one week.
Linda is a very friendly host and the apartment offered everything we expected and needed. It was clean and cozy. The apartment is also near a train station and some small supermarkets. To the promenade it's only about 3 minutes. The city square where many restaurants are is just around the corner. Because of that and the street in front, it's also a bit loud at night, but that carries less weight.
All summarized I can gladly recommend this accommodation for a stay. :)
