Francesco's flat is situated in a great spot easily walkable to the old town and basically anywhere in Polignano (it's such a small and quaint town!). He was very helpful with information before and after we arrived, helped us park our car, choose restaurants and even when I left my passport in the flat after checking out!
The flat is very clean, spacious and perfect for a few nights stay. The only thing to be aware of is the road outside can be quite busy and there is some traffic noise at night. Easily hidden though by the gentle hum of the AC!
