The most I appreciate the location of the apartment and the helpfulness of the host. The description of the apartment from the host is accurate, as well as the photos. The flat was very clean.
The apartment is within walking distance of a free beach (spiaggia Pane e Pomodoro) and of the historical centre. I would recommend you a trip - taking a direct train from the train station Bari Centrale (15min walk from the flat) to a beautiful city Polignano a mare.
The experience can of course differ according to your preferences and circumstances. For me the most important was to find something within walking distance from the beach, as from my experience the transportation by bus in Italy is not very reliable, and I was looking for an accommodation that I could afford on my own and that would offer a non-shared bathroom and kitchen (I didn't want to share it with other guests). So, this apartment met my request. I was there on my own (1 person) and I speak fluent Italian, so I communicated in Italian.
The host was ready to help me with everything and there was no problem with arranging the check-in, as I needed to arrive after the stated check-in hours. We even spent a nice day on the beach with the host and her family together. For me, the Bari experience was great.
