If you are looking for a clean place with a good location to take a shower and sleep, this is your place.
When you arrive at Bari airport you can take a train serviced by Ferrotramviara Spa to Bari Centrale. The apartment is located only 15 minutes away walking from the central station.
If you arrive early in the morning and have one full day in Bari - this will be plenty of time. I will share with you how we were getting around and which cities we visited during our stay.
On our second day, we visited the city called Matera. We took a train to there. You can catch it from the second level over the train to the airport. You can spend one day in the city of Matera.
On our third day, we took the bus to Alberobello. You can catch the bus from the street behind the Bari Centrale station - Via Giuseppe Capruzzi. Half-day is enough to walk around the city and you can have the night for Bari.
On our fourth day, we visited Polignano a Mare and Monopoli. They have really nice beaches and are only 30 minutes away by train. You can catch the train serviced by Trenitalia.
You can visit a lot of places around. I really recommend this apartment. It has a good location, it was really clean and a few stores in the neighborhood.
