Let's start with the most important point : Ada is a lovely woman, very welcoming and has a lot of tips. She lives next door, cleans and refresh the room when you are out. Besides the location is just perfect in the very center of Polignano, with a rooftop and view on the sea, just a few steps from centrale place of old town. You cannot park here but there a quite a lot of streets outside of old town (at least 500m from the appartment).
The building where you stay is very charming and colorful, one bedroom on the ground floor and about 5 more on the 2 upper levels (and on top of that, the rooftop terrace).
We were staying in the ground floor bedroom and to be honest the experience was not 5*, it is very very noisy, the street is crowded and there are also the other guests of upper floors that go back and forth in front of your door. The room is tiny, well decorated and organized, has no window so no sunlight. If you have the chance to stay at Ada's place, we highly recommend to stay on the upper floor and not booking the bedroom on the ground floor.
