We spent a wonderful time in Michele&Katia's apartment. The place is beautiful, very cozy and with all the amneties you may need. Also is within walking distance to Bari vecchia.
Michele and Katia were extremley helpful and communicative: they kept our luggage because we arrived very early, we asked for umbrellas - they left us 2 in the apartment, we asked for a parking nearby - helped us with a great parking lot near the apartment and we found in the apartement when we checked-in : water, juice, milk, coffee, tea, honey, shower gel, etc.
Definitely would stay here if we come back to Bari.
