Hotel recommendations in Ceglie Messapica, Lecce, and Bari Italy; one day tours recommendations?

Hi,
I am taking a 10 day cooking class/tour based in Ostuni. I will be spending another 3 weeks split between Bari, Lecce, and Ceglie Messapica. I am active on booking . com. Do you have any recommendations for centrally located hotels in these cities? Solo traveler.
