Overall OK.
Good sides: location was perfect - the area was fine and I felt safe (and in general, as I understood Bari is not the safest place - watch your bag and belongings). The hotel is very close to a lot of restaurants and about 15-20 mins on foot from the Bari railway central station, as well as very close to the old town. Really nice and helpful stuff, I liked all of them. Michaele at the breakfast was my favourite :) Room and bathroom were clean. Rooms were cleaned every day, and towels were changed.
Negative sides: The biggest disappointment was the breakfast - the "restaurant" is like a very small room, with 6 small tables, no space at all. There was a lack of variety in the food - I cannot start my morning without eggs and vegetables. There weren't any vegetables, which I find strange - this is the first hotel I stay in, where the breakfast is so poor.
We had only 3 nights in the hotel, so we are pretty happy with the value for the money we paid. But if you are planning a longer stay you might reconsider other options.
