I stayed at the B&B for one night. Reservation went smoothly, the hosts welcomed me very friendly, offered me coffee and we had a little chat while the room was being cleaned (I arrived before normal checkin time).
The apartment is a 10 min walk from the train station, right in the center of Bari.
The room was spacious, clean, nicely furnished, with a balcony facing the quiet backyard, air conditioning, TV. The bathroom was also very nice, big and clean.
In the small bar around the corner I had a cornetto, coffee and juice for breakfast, that was included in the room price.
I can absolutely recommend the B&B melo!
