I loved this apartment. It's not as big as the photos suggest, but that is the same for all airB&B places. However for one person, like myself, a couple or maybe a small family it was perfect - the living area is spacious. The balcony is the star of the show. wow.
There is a viewing area right next to the balcony and most of the day it is full of people. But this didn't bother me and if I positioned my chair on the left hand-side no-one could see me anyway.
Polignano a Mar is super touristy. But the apartment itself compensated for this. The beach is beautiful but personally I did find it too busy, and the rocks a little difficult to navigate. However 30 minutes walk away I discovered Cala Sala - a small inlet that was divine. It too was also stoney but if you entered via the end of the small quay you could bypass the stones and enjoy the water. What a place!
