Stefano is a great host, indeed. The place is just as expected - absolutely perfect, especially for a family - great value for money, I could say. It is close to all kinds of amenities (1 minute to the supermarket/ pizzeria/ gelateria/ bakery/ cafe, and Bari Centrale, the shopping district or the old city are in reach within a 10 minutes walk). The Panna and Pomodoro public beach is situated at approx. 30 minutes by foot (and we really enjoyed it, the sand was fine and the water quite clean), but I could not give any more details, since we have only been to the beach on our last afternoon in the city. We traveled a lot, in different cities (Poligniano a Mare, Monopoli, Altamura, Matera, Trani) by train, so the position of the apartment was amazing for us. The place is quiet but close to anything you could want, child friendly and clean, with a small kitchen that could help you make a great breakfast, each day, before heading out into the city. I do not know about the bus stations, since we didn't use them (I can only presume they were near), but this place is quite the gem, if you are a walker - at least.
We highly recommend this apartment, and Stephano - as a truly amazing host. We were impressed by his hospitality and support, throughout our stay.
Would definitely come again.
P.S. We traveled with our 2 years old daughter and she was just as thrilled about the experience. :)
