We really had a great time in Floriana's appartment. It's very clean and nicely decorated and the terrace is lovely to catch some sun in the morning. You can see the sea from your bedroom.
Floriana gave us a lot of recommendations for restaurants, shops, cities to visit etc. She also arranged a driver for us who drove us to the airport.
All kind of shops are just around the corner and the central station and city center are a 20 min walk away but we mostly took the bus. You can reach Polignano a Mare and Monopoli from Marconi station, which is just at the end of the street.
We definitely recommend this place!
