I booked 3 weeks at CConfort Hotel as I was travelling to Bari for work, and the price and the location here was very good.
My stay went well. The hotel is well located, 5 min walk from the train and bus station, 10 min from the sea front and 15 min from Bari Vecchia (historical center).
If you have any questions, they respond quickly and help without any problems.
The cleaning is done every morning in all the rooms. Which is really nice.
One small point to improve, the utensils in the kitchen.
Otherwise it was great.
If you are looking for a nice little hostel, don't hesitate.
Bari and the hostel are nice places to stay
Grazie Mille
