One of my best hostel experience as the place is kept very clean and the staff is super friendly and helpful. The bathroom is also very tidy and clean. As it is not a big bathroom with various WCs and showers, you do have some privacy for shower which I find very nice.
The hostel is located very close to the train station so it's very easy to get around. Probably also for that, you can also hear the traffic and some noises from the street, but this is not a problem of the hostel, but a trade off for staying in the middle of a big city like Bari.
