Our stay at Marialessandra was really pleasant. The place is super central in Polignano and the view from the balcony is just amazing. Marialessandra was super helpful and suggested us a couple of local places to eat / buy food to cook and eat on the terrace. I read in some reviews that the street outside the apartment can be very noisy, we stayed there mid September (Thursday to Sunday) and we did not have any problem with noise at night, so it might be depending on the season.
